[AD] msvchelp

[Milan Mimica <milan.mimica@xxxxxxxxxx>]

There is a bug in msvchelp.exe program that converts long paths to short 
format. It cannot find the supplied "MSVCDir" env variable because all 
variables on windows are caps insensitive (probably just converted to 
all caps internally) and getenv() is caps sensitive. Attached patch 
fixes the problem by converting the supplied env variable to all caps.
