Hello Thomas,
some operating systems provide already an implementation of binary
semaphores with a compatible API, e.g. RTEMS. It would be nice if I
could use it in libstdc++. I guess you don't want to have #ifdef
__rtems__ stuff in this code. What about defining a binary semaphore API
for gthr.h and then implement the optional futex support in
libgcc/gthr-posix.h?
