/* Simple implementation of vsprintf for systems without it.

   Highly system-dependent, but should work on most "traditional"

   implementations of stdio; newer ones should already have vsprintf.

   Written by Per Bothner of Cygnus Support.

   Based on libg++'s "form" (written by Doug Lea; dl@rocky.oswego.edu).
