      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 (at) rocky.oswego.edu).
