+Subject: [PATCH 1/4] implement libc specific _reopen_stream
+
+musl defines stdin/stdio/stderr as constant types which means
+we can not assign to them as we are doing here but works ok with glibc
+therefore abstract out the _reopen_stream definition depending upon if
+we are using glibc or otherwise

+Subject: [PATCH 2/4] use PTHREAD_MUTEX_RECURSIVE instead of
+ PTHREAD_MUTEX_RECURSIVE_NP
+
+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.
