/* 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).
