+ *       addition to stdarg.h and others). The GCC version is more
+ *       complex, to deal with many alternate systems, but it is
+ *       probably more trustworthy overall. It would probably be

+ * NOTE: These are incompatible with the versions in stdarg.h and should
+ *       NOT be mixed! All new code should use the ANSI compatible versions.
