| 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). |
