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:
http://mail.python.org/pipermail/distutils-sig/2003-November/003514.html
