             Bug #: 15404
           Summary: Two conflict defines for __sigsetjmp in pthread.h and
                    setjmp.h
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
        AssignedTo: unassigned@sourceware.org
        ReportedBy: guojiufu@gmail.com
                CC: drepper.fsp@gmail.com
    Classification: Unclassified


the prototype of sigsetjmp in pthread.h and setjmp.h are  little different.
/usr/include/pthread.h:
extern int __sigsetjmp (struct __jmp_buf_tag *__env, int __savemask) __THROW;

/usr/include/setjmp.h:
extern int __sigsetjmp (struct __jmp_buf_tag __env[1], int __savemask) __THROW;

These two defines are not compliant to each other in C++ aspect. So would you
please change them to the same prototype?

In which way do they conflict?

There is no cvtest namespace.  Please provide a complete, self-contained test
case.

Closing as we did not received a testcase in five months.
