           Summary: Apparent typo in gcc/include/internal/stdio_core.h
                    causing gcc compilation failure
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P1
         Component: c
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: rrr6399 at futuretek dot com
                CC: gcc-bugs at gcc dot gnu dot org

I'm compiling gcc 3.3.1 on an Irix 6.5 system with gcc 3.3. During the the 
compilation process, the compiler complained that __gnuc___gnuc_va_list _ap
wasn't defined in gcc/include/internal/stdio_core.h. 
I noticed that __gnuc_va_list was defined so I just assumed there was
a typo and changed it to this:

   319 /*__SGI_LIBC_NAMESPACE_QUALIFIER __gnuc___gnuc_va_list _ap; buggy line* /
   320      __SGI_LIBC_NAMESPACE_QUALIFIER __gnuc_va_list _ap;

I didn't use any special configure arguments except --prefix.
