[En-Nut-Discussion] Floating Point Memory Usage

Realized today that floating point eats an automatic 16K of ram on the first call to _sbrk(). I should read the manuals...

It looks like setting LIB_HEAPSIZE to 4K will work (at first, anyway), but am I setting myself up for other problems?

Without the default 16K, is 'newlib' likely to misbehave somewhere else?
