As an extra bonus, gcc-3.2.3 on solaris (same machine) appears to be fubared
when it comes to largefile support as well. Even if you don't define anything on
the command line, gcc -v reveals that it defines both -D_LARGEFILE_SOURCE=1 and
-D_LARGEFILE64_SOURCE=1 which completely breaks largefile support if you just
want _LARGEFILE_SOURCE and not _LARGEFILE64_SOURCE, you can't have it.
gcc-3.3.3 at least avoids this issue. (This is why it's a bit pointless to test
with gcc-3.2 -- the extra define drops the #pragmas from the output anyway)

Confirmed with GCC 3.3 and GCC 3.4 However, such a kind of pragma is documented
as available only in C and Objective-C; nothing is guaranteed for C++.

Normally, I might agree that this makes it technically 'not really a bug'.
However, it's being used in the processed system headers that g++ is including,
so it either a) ought to work or b) shouldn't be being used in those headers at all.
(You imply that all the pragmas defined in the docs C-extensions part of the
docs only apply to the C compiler and not the C++ compiler. Is this really the
case?)
#pragma redefine_extname is used in both stdio.h and rpc/svc.h in the processed
gcc includes. The idea that stdio.h should behave differently depending on
whether you're using gcc or g++ is, um, surprising at best I think!

Yes, it ideally should work. It certainly works with the Sun C++ compiler.

I think so. They are implemented in c-pragma.c, which AFAICS is not linked in
the C++ compiler.

The problem is, this pragma stuff is a C hack and I don't know how much work
would be required to make it work with C++.

I believe it is linked into the C++ compiler -- it's pulled in by
gcc/gcc/cp/config-lang.in I think.
$ strings cc1plus | grep redefine_extname
malformed #pragma redefine_extname, ignored
junk at end of #pragma redefine_extname
#pragma redefine_extname conflicts with declaration redefine_extname
looks conclusive.

Would replacing it with #define X Y be sufficient? The sun c-compiler docs say:
--------
#pragma redefine_extname old_extname new_extname
The pragma causes every externally defined occurrence of the name
"old_extname" in the object code to be "new_extname". Such that, at link time
only the name "new_extname" is seen by the loader.
If pragma redefine_extname is encountered after the first use of
"old_extname", as a function definition, an initializer, or an expression, the
effect is undefined. (Not supported in -Xs and -Xc modes.)
--------
This looks to me like you could replace it with #define (in system headers at
least) without any semantic change in the code as a result.
Better if it could be fixed of course.

Indeed, thanks for the correction.
And it turns out that it worked at some point (at least GCC 2.95.3):
gax% g++295 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -o pr14962 pr14962.c
gax% elfdump pr14962 | grep statvfs
[13] 0x00020870 0x00000000 FUNC GLOB D 0 UNDEF statvfs64
[69] 0x00020870 0x00000000 FUNC GLOB D 0 UNDEF statvfs64
so we have a regression.

------- Additional Comments From ebotcazou at gcc dot gnu dot org 2004-05-04 08:06 -------
I think you slightly misunderstood the semantics of #pragma redefine_extname
when you said: "I've then edited both files to comment out the definitions of
statvfs and fstatvfs. This should make no difference to the compilation, since
these names have been redifined by the pragma immediately preceeding them to
statvfs64 and fstatvfs64 (due to the -D options I added to the compiler flags)".
This does make a difference: the pragma redefines the *external* name only, not
the internal name used within the compilation unit. You didn't see the problem
with the C compiler but passing -Wall would have given:
statfs_test.c:10: warning: implicit declaration of function `statvfs'
Of course this is a hard error with the C++ compiler. So you can't comment out
the declaration of the functions, even if they have been "pragma-ized".
A good news is that the mechanism is not that broken in the C++ compiler. For
example, it works for the following code:
#pragma redefine_extname old_name1 new_name1
extern "C" int old_name1(void);
extern "C" int old_name2(void) asm("new_name2");
int foo1(void)
{
return old_name1();
}
int foo2(void)
{
return old_name2();
}
The assembly contains new_name1 and new_name2 only.
The mechanism doesn't work with your testcase because of an identifier
overloading problem. We have:
typedef struct statvfs {
unsigned long f_bsize;
unsigned long f_frsize;
fsblkcnt_t f_blocks;
fsblkcnt_t f_bfree;
fsblkcnt_t f_bavail;
fsfilcnt_t f_files;
fsfilcnt_t f_ffree;
fsfilcnt_t f_favail;
unsigned long f_fsid;
char f_basetype[16];
unsigned long f_flag;
unsigned long f_namemax;
char f_fstr[32];
unsigned long f_filler[16];
} statvfs_t;
pragma redefine_extname statvfs statvfs64
int statvfs(const char *, statvfs_t *);
If you change "statvfs" to anything else in "struct statvfs", "statvfs64" will
be emitted in the assembly output instead of "statvfs" for the function call.
Now we have to devise a fix...
