Hi!

How about the attached patch? I've tested and everything is fine. It's of course a modified version of patch from Corina, but with removed condition of size optimization.

Now each entry to _vfprintf_r() costs only about 190 bytes and __sbprintf() allocates about 1150 (on ARM Cortex-M3).

4\/3!!
