The 6.4.2 compiler was built with by the hc-build script which uses


in, so I assume it has optimization on.  Can I simply add

GhcRtsHcOpts += -O0

or should I change SRC_HC_OPTS with


in the of the 6.4.2 tree?  I'm also assuming that I can
just rebuild 6.4.2 with optimization off on the target amd64 box
and that I can still use my original .hc files from the i386 machine.
Is that true?
