[issue7639] bdist_msi fails on files with long names

[Christoph Gohlke]

Christoph Gohlke <cgohlke at uci.edu> added the comment:

I can confirm this issue. It prevents building a IPython msi installer on Python 2.6 for Windows. 

A patch to the Directory.make_short function in msilib\__init__.py is attached. It falls back to generating prefix~pos filenames when a short name is already taken and also generates short names more similar to Windows/NTFS.
