OK, here is the patch to vfprintf.c produced by diff -up.

Initially, we've added these changes to Newlib-1.11.0. They was tested 
with Newlib-1.11.0 too. But then I've copy changes to Newlib from CVS. 
vfprintf.c from CVS differs from Newlib-1.11.0's vfprintf.c. I didn't 
test (even compile) Newlib from CVS with these patch, but it must work.

Thanks.
