Well, with ``-O -fexpensive-optimizations -pipe -mcpu=i686 -march=i686'' compiling sql/sql_yacc.cc only took 26 minutes of one of the two PII-300 cpus I have. The machine has 320Mb of RAM and it did not even touch the swap. This is on 4.0, mysql-3.22.32 server port, patches/patch-aq removed... The source file is huge -- 414615 bytes... The resulting object file -- 424040. -mi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
