Interesting.  I hadn't thought there was that much of a difference (after
all, it's the same hardware, same software, same OS, etc).  I'll keep
this in mind.

Oh.  Figures.  "Core addresses" doesn't sound like POSIX would like it.

Oh.  Mingw32 doesn't have mmap()?  Yuck.

So, is it easier to "undo" the Mingw32 overwrites, or is it easier to
just uninstall everything and reinstall Cygwin cleanly?

Must be nice.  :-)

I have to be able to hand instructions to a group of people that don't
know or care about compilers, saying, "Install these programs, such as
Cygwin full.exe and the Mingw32 package, and our utilities will then
configure/build out-of-box for us."

So while the tweaking and cross-compiling is fine for my own use (and
is in fact a lot more interesting to me than my real job), I can't
apply it as a final solution.  Nor can I even try it, since I don't
have any other machines to /easily/ test on besides my own.

I thought that this was going to become the default, so that the
cygwin1.dll wouldn't be required?
