Hello,
Attached is an updated patch for Ada with GNU/Hurd, returning zero for the
functions not yet
implemented: pthread_mutexattr_setprioceiling, pthread_mutexattr_getprioceiling
and pthread_setschedparam. The new patch removes the stub warnings when building
gcc and for code using these functions.
This patch also applies to gcc-6, so a separate bug report will be submitted to
the latest version in experimental. Best solution would be if this patch can be
accepted upstream, and will be attempted in parallel.
Thanks!Index: gcc-5-5.3.1/src/gcc/ada/s-osinte-gnu.adb
