Thomas Heller 9436a75e4d Compile the files in the same order they are passed to the compiler.
Use case: Sometimes 'compiling' source files (with SWIG, for example)
creates additionl files which included by later sources.  The win32all
setup script requires this.

There is no SF item for this, but it was discussed on distutils-sig:

# This implementation by Lyle Johnson, based on the original msvccompiler.py
# module and using the directions originally published by Gordon Williams.
# XXX looks like there's a LOT of overlap between these two classes:

# WindowsCCompiler! --GPW
# This module should be kept compatible with Python 1.5.2.
