   4 Subject: [PATCH] Adding ability to detect non-posix extensions for pthreads
   5
   6 Theres a desire to build rngd with musl, which doesn't have all the gnu
   7 extensions (but it has some).  So test for those.  Note, this requires
   8 the addition of the USE_EXTENSIONS macro to enable -d_GNU_SOURCE
