	Okay I'm convinced.  I did some work on a vfprintf.c module. 
I'll post it shortly for review, however I'd prefer not to tackle
libiberty.  Either someone else should handle that, or I can add code to
link in just gcc/vfprintf.c if autoconf determines vfprintf() is
missing.  (Eg, using AC_REPLACE_FUNCS.)
