[Bug fortran/15234] New: [tree-ssa] libgfortran doesn't compile on Tru64 UNIX

[gcc-bugzilla at gcc dot gnu dot org]

Bootstrapping the current tree-ssa branch with gmp 4.1.3 (and thus gfortran
enabled) on Tru64 UNIX V5.1B fails compiling libgfortran/runtime/environ.c:

In file included from /vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/runtime/environ.c:26:
/vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/libgfortran.h:75: error: parse error before "GFC_INTEGER_4"

This happens because there is no definition of int32_t and similar types
anywhere.  While there is one in <inttypes.h> and there's even a configure
test for that header, it isn't used anywere.

Obviously, libgfortran needs to make sure that a definition of those types
is available at configure time and provide one itself if not.

While a trivial patch to use that file in libgfortran.h gets me a little
bit further, I immediately hit another error:

/vol/gnu/src/gcc/gcc-tree-ssa-dist/libgfortran/runtime/../io/io.h:282: error: conflicting types for 'unit_t'
/vol/gcc/obj/gcc-3.5-tree-ssa-20040429/5.1b-gcc/gcc/include/sys/types.h:595: error: previous declaration of 'unit_t' was here

In fact, AFAIK the *_t types are reserved by POSIX.1 and thus cannot be
used without risk of conflict.

Environment:
System: OSF1 bartok V5.1 2650 alpha
Machine: alpha
	
host: alpha-dec-osf5.1b
build: alpha-dec-osf5.1b
target: alpha-dec-osf5.1b
configured with: /vol/gnu/src/gcc/gcc-tree-ssa-dist/configure --prefix=/vol/gcc --with-local-prefix=/vol/gcc --disable-nls --host alpha-dec-osf5.1b --build alpha-dec-osf5.1b --target alpha-dec-osf5.1b --disable-libmudflap --with-gmp-dir=/vol/gnu/obj/gmp-4.1.3

How-To-Repeat:
Try bootstrapping the tree-ssa branch on Tru64 UNIX V5.1B with gmp.
