sys/cdefs.h. In particular, in case of COMPAT_43, param.h includes
sys/types.h, which includes sys/select.h, which includes
sys/_sigset.h. The _sigset.h customizes the provided definions based
on COMPAT_43, eliminating osigset_t if symbol is not defined. The
sys/proc.h is included after opt_compat.h and needs osigset_t.
Move opt_compat.h inclusion into the right place.
