gcc4.5.0/libiberty/pex-common.h missing pid_t on vms

/src/gcc-4.5.0/libiberty/pex-common.h:73:3: error: expected specifier-qualifier-list before 'pid_t'


the code:

/* pid_t is may defined by config.h or sys/types.h needs to be
   included.  */
#if !defined(pid_t) && defined(HAVE_SYS_TYPES_H)
#include <sys/types.h>
#endif


proposed/tested fix:
#ifdef __vms
#include <unistd.h>
#endif

or similar.

This then hits:

/usr/local/lib/gcc/alpha-dec-vms/4_5_0/../../../../alpha-dec-vms/include/unistd.h:475:22: error: macro "geteuid" passed 1 arguments, but takes just 0
/usr/local/lib/gcc/alpha-dec-vms/4_5_0/../../../../alpha-dec-vms/include/unistd.h:476:22: error: macro "getuid" passed 1 arguments, but takes just 0
make[2]: *** [pex-common.o] Error 1


But I say that's a bug in the VMS headers and I patch it:

#if __USE_LONG_GID_T
#   pragma __extern_prefix __save
#   pragma __extern_prefix "__long_gid_"
#elif __CRTL_VER>= 70000000 && !defined(_VMS_V6_SOURCE)
#   if __CAN_USE_EXTERN_PREFIX
#      pragma __extern_prefix __save
#      pragma __extern_prefix "__unix_"
#   else
-#    define geteuid() __unix_geteuid()
-#    define getuid() __unix_getuid()
+#    define geteuid __unix_geteuid
+#    define getuid __unix_getuid
#   endif
#endif


__uid_t geteuid (void);
__uid_t getuid  (void);


I did the same thing in the VMS header unixlib.h.
Maybe something for fixincludes? (along with #define __NEW_STARLET, #define __int64 long long...)


(Alternate interpretation is that gcc should implement __CAN_USE_EXTERN_PREFIX
and the #pragmas. I'd be willing to #define __USE_LONG_GID_T but I assume the pragmas are a problem.)
