This test shows the problem that msi is having installing .Net 1.1.

Could someone familiar with this code have a look at it please?

It seems we need to check for second param being NULL and if so, return
error. At least that's what MSDN implies.

I just verified on Windows XP Pro SP2 that GetShortPathName with a NULL 
second variable does return a proper length and does not set an error.  
This is the behavior that the msi code using this function expects.
