+Subject: [PATCH] third_party/threads: Use PTHREAD_MUTEX_RECURSIVE by default
+
+PTHREAD_MUTEX_RECURSIVE_NP was used for compatibility with old glibc.
+Although due to the_GNU_SOURCES define the portable,
+PTHREAD_MUTEX_RECURSIVE will be available for Linuxes since at least
+1998. Simplify things giving us compatibility with musl which
+apparently does not provide the non-portable define.
+
+Inspired by almost identical commit in mesa aead7fe2e2b(c11/threads: Use
+PTHREAD_MUTEX_RECURSIVE by default) by Felix Janda.
