[Samba] Visual C++ crashing using precompiled headers on a Samba

Bill Hilf of Microsoft helpfully sent me this information
about the problems people were having with Visual C++ compilations
crashing on a Samba drive (when the "allocation roundup" parameter
is left at the default setting).

So - the real info is that pre-compiled headers are only supported
by VC++ on the same machine that creates them. If you create a project
on a local drive and then copy it to a Samba share it may fail. If
you want pre-compiled headers to work create the project on the
Samba share to start with (or set "allocation roundup = 0").
Thanks to Bill for this info,
