gcc/fortran/cpp.c contains:

  /* FIXME: Pandora's Box
    Using the macros below results in multiple breakages:
     - mingw will fail to compile this file as dependent macros
       assume to be used in c-cppbuiltin.c only. Further, they use
       flags only valid/defined in C (same as noted above).
       [config/i386/mingw32.h, config/i386/cygming.h]
     - other platforms (not as popular) break similarly
       [grep for 'builtin_define_with_int_value' in gcc/config/]

  TARGET_CPU_CPP_BUILTINS ();
  TARGET_OS_CPP_BUILTINS ();
  TARGET_OBJFMT_CPP_BUILTINS (); */


Grepping for builtin_define_with_int_value shows:

gcc/config/frv/frv.h
gcc/config/i386/mingw32.h
gcc/config/mips/mips.h
gcc/config/freebsd-spec.h


Expected: The macros which make only sense for C are only used for C, e.g. many
of the __attribute__(()) ones.

------- Comment #2 from burnus at gcc dot gnu dot org  2010-02-04 14:06 -------
Daniel: Wouldn't it be enough to duplicate c-cppbuiltin.c's
builtin_define_with_value and builtin_define_with_int_value for fortran/cpp.c?
Regarding builtin_define_std: Couldn't one simply define __<TXT> and __<TXT>__
(after stripping leading _) ignoring the unmodified version?

I tried this but it fails on x86-64-linux with:
  cpp.c:(.text+0x1d6b): undefined reference to `ix86_target_macros'
which is the file gcc/config/i386/i386-c.c for
  #define TARGET_CPU_CPP_BUILTINS() ix86_target_macros ()

------- Comment #4 from burnus at gcc dot gnu dot org  2010-03-17 09:31 -------
Cross reference: The missing define of "_WIN32" causes failures on
MinGW/MinGW64 for gfortran.dg/dev_null.F90 and gfortran.dg/write_to_null.F90.
(cf. PR 42950 which is otherwise fixed.)

Created an attachment (id=21373)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=21373&action=view)
Patch for fixing at least target part for preprocessor

This patch re-enables at least target defines for fortran's preprocessor.
The architecture part isn't enabled, as for example i386's architecture
preprocessor settings are at the moment just working for C/C++ frontends.
