Summary: distutils ignores environment variables

Initial Comment:
Visual C++ 6.0 sets up environment variables for use 
by command-line users -- MSDEVDIR, INCLUDE, LIB.  It 
also provides VCVARS32.BAT to set these environment 
variables.  They specify where to find cl.exe and its 
header files and libraries.

distutils ignores those in favor of the registry.  I 
think distutils should honor the environment variables 
if they are set.

In my case, the registry was pointing to an old, 
removed install of VC.  I later installed a new 
version in a new location, but that install did not 
modify the registry.

Jeremy, do you know how to run regedit?  It's a GUI 
registry browser.  Do Start -> Run and type "regedit" (no 
quotes) then click OK.

I want you to navigate to two places:

HKEY_LOCAL_MACHINE\
Software\
Microsoft\
Devstudio\
6.0\
Build System\

and exactly the same except starting at HKEY_CURRENT_USER 
instead.

My *bet* is that you're going to find that path in both 
places, but that under HKEY_LOCAL_MACHINE it's pointing to 
a wrong place.  This would be a side-effect of not having 
properly uninstalled your previous MSVC.

If that's all true, select the DevStudio node under 
HKEY_LOCAL_MACHINE and then do Edit->Delete.  This will get 
rid of the obsolete registry setting.  Close regedit then.

disutils *should* look under HKEY_CURRENT_USER before 
looking under HKEY_LOCAL_MACHINE, because per-user settings 
are suppused to take precedence over per-machine settings, 
and especially under Win2K.  That appears to be a repeated 
buglet in msvccompiler.py.
