+Changes needed to get GnuPG estream.c to compile with the Studio C compiler.
+
+These were legitimate bugs in GnuPG version 2.0.22, but looking at the
+latest version of estream.c in the GnuPG git repository, the problems have
+been resolved by redefining ESTREAM_MUTEX_UNLOCK and ESTREAM_MUTEX_INITIALIZE
+to no longer test against estream_pth_killed and therefore no need for the
+bogusly defined dummy routines.
