This will implicitly disable optimizations, I think. If you set CFLAGS,
you will need to add "-g -O2" to the CFLAGS. You can rebuild just in
libguile/; the .go files are fine and don't need any rebuild. Could
this be the issue?
GCC 4.4 is of course a very old compiler, but you probably know that :)
