The Fortran people are interested in this. For full F2003 support, we need the
Fortran front-end to know during code generation which integer mode correspond
to certain C integer types, including the int_fastN_t, intmax_t and size_t
types.

C++ folks also. Note that GCC_HEADER_STDINT(gstdint.h) solution is used by:

libgomp
libgfortran
libdecnumber

and soon by libstdc++. This does use the native stdint.h when possible. 

I'm with Geoff in that another stddef.h macro-nest is to be avoided. That file
is ridiculous.

------- Comment #10 from jsm28 at gcc dot gnu dot org  2008-04-15 19:44 -------
GCC allows duplicate typedefs in system headers, which should simplify this
header a bit.

See http://gcc.gnu.org/ml/gcc/2008-03/msg00558.html for the latest partial
attempt at giving the compiler knowledge of these types, and my followups on
how to handle OSes where GCC lacks knowledge of the types but the OS might have
some or all (don't provide the header), OSes where a newer version has the
types (take the types from the newer version) and unmaintained OSes or OSes
that otherwise won't be updated to have these types themselves (only in that
case make a GCC-local choice of types).

------- Comment #11 from jsm28 at gcc dot gnu dot org  2008-04-18 14:15 -------
When GCC knows about these types on a target, CHAR16_TYPE and CHAR32_TYPE
should be defined to be the same as uint_least16_t and uint_least32_t.

Note that the patch committed does not completely fix the issue; work
is needed for each target to tell GCC about the types on that target, and
the patch only does that for glibc/uClibc, newlib and Solaris.

Errors are expected until someone adds the relevant type information for 
Darwin to GCC and fixes any bugs in its system stdint.h.

This means there is something wrong with the definitions of intptr_t, 
uintptr_t and their limits in the system stdint.h.  It can be fixed in GCC 
with fixincludes, but should also be reported upstream.

Either the size_t limits are wrong or GCC disagrees with the system on 
what type size_t should be.

The Darwin header wrongly uses unsigned types for the results of UINT8_C 
and UINT16_C.  Report the bug upstream (with reference to C99 TC1), fix 
with fixincludes.

These will fail until GCC knows internally what the types are.

Adding the libstdc++ regressions I've seen as a dependent, see PR39644 comment

(That is, the PR448 solution in progress relies on newlib providing the missing
INTPTR_MAX, INTPTR_MIN and UINTPTR_MAX which it doesn't do - yet.)

Thanks for pointing this out - the intptr_t and uintptr_t types are 
optional, but the limits are required if the types are provided.  I'll 
look at adding extra testcases verifying that GCC and the header agree on 
whether the limits are available.  Someone should also fix newlib upstream 
to provide the limits and add appropriate fixincludes to GCC to fix older 
newlib headers.

------- Comment #20 from paolo dot carlini at oracle dot com  2009-07-31 12:40 -------
I'm wondering if there is something we can/should do here about C++1x: in the
new Standard (see 18.4.1/2 in n2914, for example), for <cstdint> we have:

The header defines all functions, types, and macros the same as C99 7.18. [
Note: The macros defined by <cstdint> are provided unconditionally. In
particular, the symbols __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS
(mentioned in C99 footnotes 219, 220, and 222) play no role in C++. —end note ]

and since the implementation of <cstdint> can, conformingly, include <stdint.h>
and do little more, I would guess a little of support in <stdint.h> to its C++
uses would make the life of the implementors *much* easier...

For the record, at the moment we are just defining the macros as part of
<cstdint>, at the top, before including <stdint.h>, but of course the solution
isn't too good, it breaks immediately if the user code for some reason includes
<stdint.h> before <cstdint> without defining the macros.

I would suggest predefining those macros in C++1x mode; that should make 
things work with all existing stdint.h implementations that care about 
those macros.

If you need help beyond that - for example, to ensure that each of 
<stdint.h> and <cstdint> puts things in the right namespaces - then 
stdint-gcc.h could certainly be adjusted to know about C++ requirements, 
but systems with their own stdint.h generally only use stdint-gcc.h for 
freestanding compilations so further help from libc implementors may be 
needed.

Note, in C++1x, those macros should be effectively predefined *only* when
<cstdint> is included, not when <stdint.h> is included. Thus, I agree - note
I'm not completely sure to get all your points - for those targets such as GCC
just uses the system provided <stdint.h>, I agree GCC probably can't do much...

That's not how I read N2914; it appears to say <stdint.h> is a strict 
superset of <cstdint>.

Oops, now I understand, was overlooking 18.4.2. Great. Thus we could just
arrange for those feature macros to be automagically defined when -std=c++0x
(gnu++0x). Do we have already have something similar elsewhere? I can prepare a
patch.

I'm still not completely sure that solution makes for a perfect implementation
(what happens if the user code explicitly undefines the macros?) but it would
be a progress. Then, eventually, <stdint.h> will just have to support those
C++1x uses, by ignoring the value of the feature macros when C++1x and
providing the macros unconditionally.

Something like this should be enough, barring objections, I'll polish it, add a
testcase and submit it.

The table appears to be up to date.  The note about bug 30789 should be 
removed and the note about math_errhandling updated to indicate that glibc 
now has such more limited math_errhandling implementation as can be done 
without compiler support (see glibc's CONFORMANCE file for details).

You will, in any case, need lots of target macros to allow for the 
defaults to be overridden.

The logic isn't currently present to get the type of the macros for type 
limits such as UINT16_MAX correct (when an unsigned type has a limit of 
type int because the type promotes to int), but this is easy to do.  (At 
present that logic for USHRT_MAX and UCHAR_MAX is in <limits.h>.)

The INTN_C, INTMAX_C macros also need to be defined (to concatenate an 
appropriate suffix).

Note the footnotes about __STDC_LIMIT_MACROS, __STDC_CONSTANT_MACROS and 
C++.

Equally, other headers may want to redefine the types later.  Either you 
make sure duplication is OK for both C and C++ or you interoperate with 
the existing systems used in system headers.  For example, current glibc 
uses

/* There is some amount of overlap with <sys/types.h> as known by inet code */
#ifndef __int8_t_defined
# define __int8_t_defined
typedef signed char             int8_t;
...

whereas older glibc used in some places a convention of the form

# ifndef intptr_t
typedef long int               intptr_t;
...

You should arrange for error messages mentioning definitions from the 
pragma to give the line number of the #pragma in <stdint.h> as the line 
number of both the typedefs and the macro definitions, to avoid making 
this approach too confusing.

My suggestion on how to implement this is to have stdint.h essentially contain a single line,

#pragma GNUC stdint

which defines the typedefs based on information in the machine description.  That information doesn't 
exist yet, so you'd have to add it, with suitable defaults computed from the sizes of the types (perhaps 
using the same algorithm that __attribute__((mode)) uses.  The information has to match the system's 
idea from inttypes.h, including such details as 'long' vs. 'int' even if they are both the same size.

On some systems, the same types can be defined in other headers, so the #pragma would need to only 
define a particular type if it hasn't been defined already.

You could theoretically do this with a huge collection of preprocessor macros, like stddef.h or limits.h, 
but this would be pretty painful, so don't.

A good testcase is to use -Wall and check that all the PRI* and SCN* macros from inttypes.h don't 
produce warnings when used in scanf and printf with the correct type.

Those headers are included by Solaris's <inttypes.h>.  An implementation
of <stdint.h> in GCC of course needs to be compatible with such pre-C99
system libraries providing <inttypes.h> but not <stdint.h>, and allow for
user programs to include both, probably by fixincluding <inttypes.h> to
use GCC's header rather than the internal ones.

See <http://gcc.gnu.org/ml/gcc/2003-10/msg00397.html> for my current
thinking on the implementation of <stdint.h>.  The volunteer in that
instance seems to have disappeared.

For what it's worth some systems provide the functionality in a header with a
different name. For example Solaris 8 provides a file <sys/int_types.h> and
<sys/int_limits.h> that seem to define all of the types and constants of needed
by <stdint.h>.
