Does this mean that these are all non-cygwin mingw apps?

Nope, they are cygwin-based cross development tools.

Except, apparently, the proposed build of gdb -- unless Chris S. was confused:

Which was, oddly enough, the reason I asked the question.

So, follow-on question:  Can we have one toolchain which targets both
32-bit and 64-bit?  It is certainly possible to do that on linux with
a -m32 and -m64 option.  Is it possible to do this with mingw?


yes, its possible to have multilib capability for the mingw-w64
toolchain, but only with gcc trunk 4.5.0.

There are also more issues with multilib capable toolchains, gcc target
libs clashing. For example, make install currently tries to install
both 32bit and 64bit libstdc++-6.dll into the bindir.

Its a known issue, but it has yet to be fixed.
