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
