- * varargs.h
- *
- * Old, non-ANSI facilities for stepping through a list of function
- * arguments of an unknown number and type.
- * TODO: Has not been tested. Essentially it copies the GCC version.
- *
- * NOTE: I believe GCC supplies a version of this header as well (in
- * 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
- * better to use the GCC version.
- *
- * NOTE: These are incompatible with the versions in stdarg.h and should
- * NOT be mixed! All new code should use the ANSI compatible versions.
- *
- * This file is part of the Mingw32 package.
