-mno-cygwin certainly is very good hack. I hoped I was contributing
to making it an even better hack.

setup.exe is a huge success
of cause and makes things very easy to install. I have never looked at
the mingw toolchain, but I bet the cygwin stuff is a lot easier to
install.

And with a bit of attention paid to the configure script a package can
build
out-of-the box with gcc -mno-cygwin. This is much better than the often
ill maintained mingw specific makefiles, if they are there at all.

-msolaris not, since you can buy a solaris box. djgpp comes with
a bash port and so you can run configure scripts on djgpp natively.
No need for -mdjgpp, though it would be nice to have that :)
I am not aware of a bash port for mingw. So for configure scripts
you need cygwin as host.

I would certainly hope that gcc -mno-cygwin is developed further. For
one
thing it would be nice if mingw libraries (as available at
gnuwin32.sourceforge.net)
could be installed through setup.exe.
