The changes needed to make -O work on MS-Windows are now committed to the master repository, see commits da7df54 and 049f8e8. Please review and comment. I also took liberty in committing a small change posted by Frank in this thread, whereby, if taking the semaphore fails, output is dumped unsynchronized, instead of being silently ignored. (Btw, I don't see Frank's assignment on file for Make, so I marked this change "tiny", per the FSF procedures.) Thanks to all who contributed to this (lengthy) discussion and allowed me to understand how to implement this feature on Windows. _______________________________________________ Bug-make mailing list Bug-make@gnu.org https://lists.gnu.org/mailman/listinfo/bug-make
