Not sure why the regression test missed this, but the PyXML tests caught it.

msvcrtmodule.c
/*********************************************************
msvcrtmodule.c
A Python interface to the Microsoft Visual C Runtime
Library, providing access to those non-portable, but
still useful routines.
Only ever compiled with an MS compiler, so no attempt
has been made to avoid MS language extensions, etc...
This may only work on NT or 95...
Author: Mark Hammond and Guido van Rossum.
Maintenance: Guido van Rossum.
