We don't have this (yet), the code just does `extern unsigned long 
GC_free_space_divisor;`. But still I think it's a good idea because it allows 
the user to change it, should there ever be a need.

Setting GC_free_space_divisor to 1 decreases GC time on GUILE v2 from
2.1s to 1.75s, a 17% speedup for the Mozart horn concerto example

Don't try to tune the GUILE 1.8 GC if we are on GUILE 2.

That sounds quite preferable since it removes the gc.h dependency.

This one seems like an unrelated Rietveld issue?
