OK. Just to confirm: I think the problem with current code is that when no
version is given, it does not look at any default locations. The right
approach would be to search though 7.1, 7.0 and 6.0 paths.

Also, do we need to invoke compiler/linker with the full path? vcvars32.bat
changes PATH, I believe, but there may be another "cl" in PATH...., so full
path is needed. Am I missing something?

And final question: if compiler is in the path, what should be do? Use that
one? Or ignore PATH? Should be use compiler in path even if

using msvc : 6 ;

was used? I tend to ignore PATH at all.

Could you explain what's that issue is about. I do not understand what's
wrong, if anything.

OK. That's probably next thing I'll do on V2.

But we don't make any use of PATH settings when configuring msvc.... so I
don't get your argument.
