To make it easier to read and write where it is used.

Nor in my proposal.  I'm just saying the AC_CANONICAL_HOST and case
should get into it, nothing more.

We are probably misunderstanding each other.  I don't understand what
you mean here.

It was not clear to me that ac_cc_win32 was the main point, I
understood that setting CC was the main point.

So if that's the case, then I have further comments to make.  Don't
use the ac_cc name space at all when interacting with the user.  Use
some upper case thing such as CC_MWIN32.  I have no idea about it, but
I guess the C++ compiler will also want something similar?
