Yep, and here is the problem: In the case of Clang this uses FreeBSD's <md5.h>. In the case of GCC apparently this uses our own, bare-bone md5.h - include/md5.h. Boom. Regression. Bootstrap failure on every platfor and version of FreeBSD. (FreeBSD 11.x is also broken by this patch, in a different way, alas went end of life a week ago.) I now filed https://gcc.gnu.org/bugzilla/show_bug.cgi?id=102675 and sadly don't have an idea how to tackle this. Gerald
