I just posted a longer and more general post on this.

To use some of your specifics above, in case my post was
too unclear or wandering, for instance, some of my unclarity
is that I will assume that since Comeau is being invoked in
a stricter mode with --a that all the compilers are being
invoked similarly. But I know for instance that even VC++
will choke on windows.h if it is compiled with /Za. So,
I'm confused. As well....

... although this is true, I'm wondering about this at a more
fundamental level, since I'm unclear on whether the demands across
the tools are the same.

Also, even if windows.h is removed from the build,
it appears some ctype.h'ish macros or enums (I haven't gotten to
check yet) are involved in some code, using ids such as
C1_UPPER | C1_LOWER | C1_DIGIT | C1_PUNCT | C1_ALPHA
Although I realize that simply providing their values
may be insufficient.
