Hello. I'm compiling my programs with the -std=3Dc99 switch. However the
inclusion of pthread.h from xenomai distribution causes the compilation
to fail with syntax errors.

This simple program demonstrates the problem:

#include <pthread.h>

int main(int argc, char **argv)
{
     return 0;
}

If I compile it with 'gcc -std=3Dc99 $(xeno-config --posis-cflags)' i
obtain the following errors:

Of course i do not obtain any error it i remove the xenomai specific
include directories options from the gcc command line.

Can this problem be solved? Can I help somehow?

Thanks. Cheers,
