+Subject: [PATCH] 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

+
+ # Be careful if there there are symbolic links or multiple filesystem
