#
# This Makefile fragment is included by package Makefiles and
# buildlink3.mk files for the packages that use dlopen().
#
# DLOPEN_REQUIRE_PTHREADS is a user- and package-settable yes/no variable
# whose value decides whether pthread.buildlink3.mk is automatically
# included or not. Its default value depends on whether native
# pthreads exist.
#
# Including pthread.buildlink3.mk is deferred until bsd.pkg.mk.

# dump when they dlopen a shared module that _is_ linked with pthread
