I don't know that we need a separate setting.  If you can live without
it the following patch should do the trick.  The patch causes GCC to
default to the gcc-3.2.x collection values (i.e. 30% min-expand and
4Mb min-heap) when 'gc' checking is enabled, and this setting is
already "on" by default on mainline.

	* ggc-common.c (init_ggc_heuristics): Don't use the heuristics
	when checking is enabled.
