Just ran into this.

A forgotten commit, maybe?

[Bug libfortran/40863] [4.5 Regression] Build failure in libgfortran

[burnus at gcc dot gnu dot org]

------- Comment #2 from burnus at gcc dot gnu dot org  2009-07-26 18:42 -------
Created an attachment (id=18255)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=18255&action=view)
Draft patch

Patch. As I cannot test all the combinations, I would be happy if someone could
test it or read the patch. (I will reread it and also do some testing, but by
default I am not affect by this bug.)

The problem is that the C99 fall back functions are defined in c99_proto.h, but
it is not included in intrinsics/c99*.c. Thus there is no prototype and due to
the -W* settings, there is an error.

I do not quite understand why this has not come up before. Only about 10% of
the functions had prototypes - presumably the other 90% of the fall backs are
not used...

The prototype warnings have been there foreever.  On hpux, the error
appears as a result of your change:

../../../gcc/libgfortran/intrinsics/c99_functions.c: In function 'casin':
../../../gcc/libgfortran/intrinsics/c99_functions.c:1433:11: error: 'I'

With the patch, I see the same errors and warnings on hppa2.0w-hp-hpux11.11
as reported for cygwin in comment #3.

They should be fixed with the patch ... Do they still appear?

Hmm. Do you know how the macro is called which provides "I", where I*I = -1?

On a POSIX/C99 system one has:

       The <complex.h> header shall define the following macros:
       complex
              Expands to _Complex.
       _Complex_I
              Expands  to a constant expression of type const float _Complex,
              with the value of the imaginary unit (that is, a number i such
              that i**2=-1).
       imaginary
              Expands to _Imaginary.
       _Imaginary_I
              Expands to a constant expression of type const float _Imaginary
              with the value of the imaginary unit.
       I      Expands to either _Imaginary_I or _Complex_I. If _Imaginary_I
              is not defined, I expands to _Complex_I.

Which of those macros are defined on hppa2.0w-hp-hpux11.11 and on Cygwin ?
Seemingly not the last one ...

Can you try whether the following works (place somewhere in
intrinsics/c99_functions.c):

#ifndef I
# if defined(_Imaginary_I)
#   define I _Imaginary_I
# elif defined(_Complex_I)
#   define I _Complex_I
# endif
#endif

Enhanced version with yet another version for I:

#ifndef I
# if defined(_Imaginary_I)
#   define I _Imaginary_I
# elif defined(_Complex_I)
#   define I _Complex_I
# else
#   define I (1.0fi)
# endif
#endif

This compiles on Cygwin, when applied on top of your other patch.

Good work!

Same on hppa2.0w-hp-hpux11.11.  There are no warnings.

Thanks,
Dave

FIXED on the trunk (4.5). Thanks for the bug report and sorry for the breakage. 

Feel free to open a PR if build warnings show up in libgfortran. In principle,
there should be none. (I have forgotten why we cannot use -Werror.)
