The issue is that the variables:

MSVS_ARCH
and
MSVS_VERSION

must be set before the Environment is created. When using variants  
this is done within the variant loop I believe. If the Environment is  
configured outside without using variants then things are a little  
more straight forward to correct. In general, the code that is in the  
msvs_misc function for the 64bit platform can be commented out.

Also, there are problems with detecting whether the code is being run  
on a 64 bit platform. I have been unable to find a method that works  
other than to read registry values or environment variables. I found  
notes to this affect in the scons msvs common.py file as well.

I think updating SCA to support msvc 8.0 and 9.0 for both 32 and 64  
bit platforms would be fairly straight forward. Is it OK to require  
SCons 1.2.0 for SCA use?
