#pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers
