When building with MSVC, somewhere in the process one of these
"vcvars32.bat" scripts is read in to set up environment variables that
are later used during the invocation of "cl.exe" etc. As I suppose that
script isn't read in on each invocation of an action that calls one of
the MSVC tools, I suppose some form of environment sharing has to be used.
Am I wrong ?
