Don't use it. Ports that > unconditionally use it need to be fixed. Naddy thanks, just in time! I was just discussing this with the port maintainer. Actually if I put CFLAGS= -O -pipe -ffast-math in /etc/make.conf I get stopped at the config stage: configure:3832: error: C compiler cannot create executables I cannot find much info on -ffast-math. Could you please expand on your answer. many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 928 8233 Fax: +44 (0)117 929 4423
