May be, the main Makefile > can be modified to strip ``-O[1-9]*'' from the CXXFLAGS, instead? That sounds fine, although I suppose a determined user could choose options that trigger the bug. It looks to me as though the -O options may be shorthand for combinations of -f options. The gcc info pages say: When you specify `-O', the compiler turns on `-fthread-jumps' and `-fdefer-pop' on all machines. The compiler turns on `-fdelayed-branch' on machines that have delay slots, and `-fomit-frame-pointer' on machines that can support debugging even without a frame pointer. On some machines the compiler also turns on other flags. Anyway, go ahead with your idea. -- Trevor Johnson To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
