As analyzed by Steve, on freebsd __gthread_t is a pointer type. I thought it the cleanest solution to remove the #ifdef in gfc_unit, make the "self" member a intptr_t and cast the return value of __gthread_t to that type. Sorry for breaking bootstrap... the ubiquity of Linux is really striking here. There are a couple of Regression-tested on Linux. FreeBSD should also work, but I'd like confirmation, if possible. Steve, could you be so kind? OK for trunk? Best regards Thomas PR fortran/123512 libgfortran/ChangeLog: * io/io.h: Change type of self to intptr_t. * io/async.h (LOCK_UNIT): Cast __gthread_self () to intptr_t. (TRYLOCK_UNIT): Likewise. (OWN_THREAD_ID): Likewise.
