             Bug #: 14188
           Summary: pthread_cleanup_push uses __builtin_expect when
                    !defined(__GNUC__)
           Product: glibc
           Version: 2.15
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nptl
        AssignedTo: unassigned@sourceware.org
        ReportedBy: robotux@celest.fr

    Classification: Unclassified


Greetings glibc maintainers,

in pthread.h, when __GNUC__ is not defined, pthread_cleanup_push is defined
(line 648 in 2.15) in a way that uses __builtin_expect. I think this can't
reasonnably be expected to be supported by all compilers. As a matter of fact,
tinycc doesn't support this extension and thus every program using
pthread_cleanup_push fails to compile with it.

Best regards,

Thomas Preud'homme
