--with-gc seems to be a configure-time option only, not a run-time
option. gcc's Makefile.in includes just a single object file to
implement garbage collection, e.g. ggc-simple.c or ggc-page.c, decided
by the configure script.

Unfortunately with current cygwin I am unable to rebuild a toolchain
under W98 - the configure hangs during a sed invocation. Instead I'll
have to do the rebuild on another machine which can be booted into XP.
