sprintf without realloc?

Hmm, from a quick look at the code, malloc() is really only needed
to support the "%S" and "%ls" formats (wide character strings).
It's likely you don't need this support.  So you could just create
_malloc_r and _free_r routines that always return an error.

If you do need the wide character support, then you can have
the _malloc_r and _free_r routines deal with a static buffer, or
change the vfprintf.c to use a static buffer directly.
