I think PATH is going to be the tough one.  The toolchain will need to 
find all of its dll's, and there is no way to set the path for make 
time.  I am not sure what LIB and LIBPATH are.  LIB contains paths so 
they might be the same.   I think the only way this could work reliably 
is if we ran a wrapper around the compiler/linker, etc and actually set 
the environment variables at make time.

Here is what I have to set to use cl from the command line:

export INCLUDE="C:\Program Files\Microsoft Visual Studio 
9.0\VC\ATLMFC\INCLUDE;C:\Program Files\Micro
soft Visual Studio 9.0\VC\INCLUDE;C:\Program Files\\Microsoft 
SDKs\Windows\v6.0A\include;"

export LIB="C:\Program Files\Microsoft Visual Studio 
9.0\VC\ATLMFC\LIB;C:\Program Files\Microsoft Vis
ual Studio 9.0\VC\LIB;C:\Program Files\\Microsoft SDKs\Windows\v6.0A\lib;"

export 
LIBPATH="C:\WINDOWS\Microsoft.NET\Framework\v3.5;C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727
;C:\Program Files\Microsoft Visual Studio 9.0\VC\ATLMFC\LIB;C:\Program 
Files\Microsoft Visual Studio
9.0\VC\LIB;"

export PATH=/cygdrive/c/Program\ Files/Microsoft\ Visual\ Studio\ 
9.0/Common7/IDE:/cygdrive/c/Program
\ Files/Microsoft\ Visual\ Studio\ 9.0/VC/BIN:/cygdrive/c/Program\
