1 /* Simple implementation of vsprintf for systems without it.
2 Highly system-dependent, but should work on most "traditional"
3 implementations of stdio; newer ones should already have vsprintf.
4 Written by Per Bothner of Cygnus Support.
5 Based on libg++'s "form" (written by Doug Lea; dl@rocky.oswego.edu).
