Hallo,
2012/2/15 Marc Feeley feeley@iro.umontreal.ca:
I've read in the git commits that now the default flag is -O2, could this be the reason?
It could. Please modify the configure script so that it uses -O1 and check if that works better. I would be interested in the time both ways, and the version of your gcc.
FWIW, I opened a bug[1] for GCC that, after fixed for 4.7.0, did let me compile Gambit-C with -O3 and using `make -j 3` on machine with 8GB of RAM, very quickly.
