           Summary: fixincl on Red Hat EL 5 breaks sys/stat.h fstat64()
           Product: gcc
           Version: 4.5.3
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: psmith@gnu.org


Hi all.  When I run fixincl from GCC 4.5.3 on my Red Hat EL 5 system, the
resulting sys/stat.h will throw an error whenever I try to call fstat64() from
my code.  If I delete sys/stat.h from the include-fixed directory, so the
original is used, then all is happy again.

Before fixincl the code reads:

extern int fstat64 (int __fd, struct stat64 *__buf) __THROW __nonnull ((2));

After fixincl it reads:

#ifdef __GNUC_GNU_INLINE__
extern
#endif
__inline__ int fstat64 (int __fd, struct stat64 *__buf) __THROW __nonnull
((2));

and the compiler error I get is:

include-fixed/sys/stat.h:255:16: error: inline function 'int fstat64(int,
stat64*)' used but never defined

where line 255 is the __inline__ line above.

Checking with the preprocessor I see that __GNUC_GNU_INLINE__ is built-in
defined to be 1.
