Visible in PB2 in 5.1-main for some time now.

Thank you for a problem report. What gcc version do you use?

[4 Feb 2009 20:10] Davi Arnaut

The /opt/csw/gcc3/include/pthread.h header used by gcc does not declare the pthread_setscheprio prototype, but the function is implemented.. which probably causes the autoconf check to succeed.

      Bug#42599: error: `pthread_setschedprio' was not declared in this scope
      
      The problem was that a pthread.h header used by gcc did not
      declare the pthread_setscheprio, yet the function is implemented
      by the function is implemented, causing a autoconf check to pass
      and compilation with C++ to fail. The solution is to add a
      autoconf check to ensure that the function is properly declared.
     @ configure.in
        Check that the pthread_setschedprio is declared.

Noted in 5.1.37, 5.4.4 changelogs.

configure.in did not properly check for the pthread_setschedprio()
function.

Noted in 5.4.2 changelog because next 5.4 version will be 5.4.2 and not 5.4.4.

Ignore previous comment about 5.4.2.
