Hi Paul,
thanks for the exhaustive testing.
This is due to Mac OS not (yet) including the const in:
int pthread_attr_getscope(const pthread_attr_t *attr, int *scope);
just verified: MacOS X 10.5.8 does contain the const.
nptl/glibc does contain it in the headers (but not in the man-page).
Best regards,
Rainer
