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
One question though, is there a point to having gdb? The stdin/stdout
handling is messed up a little due to it being an interactive DOS app
running within Cygwin. It works, but the command line interface can
get a little messy after a while.
OK, cross gdb can be left out for now. The gdb server won't be a cygwin
application, but gdb itself is. 32bit debugging is very much already
covered by Cygwin gcc.
My concern is this: we (cygwin) definitely need a gcc-4-based mingw
cross compiler. On which source tree shall it be based, and who will be
I can do a cross gcc-4 for plain mingw too, I just need some help for
the cygport part.
The proposal on the table is to use the mingw-64 source tree (that is,
the gcc/binutils source code as patched by the mingw-w64 project,
coupled with THIER patched version of the w32api and mingwrt runtime
libs), configured in such a way as to support 32bit $host (*).
I was under the impression, until now, that we would be using the
mingw.org version of all of that.
Binutils and GCC for mingw-w64 are vanilla FSF releases, no patches are
applied. Well, no plans to replace mingw.org gcc, as it is what most
users are used to.
Personal: the mingw-w64 guys are critical of the (perceived) lack of
user support form the mingw.org community; while the mingw.org guys are
pissed that the w64 fellas have been pushing changes into upstream
projects like gcc and binutils that sometimes conflict with the

It looks like we have no choice but to choose, as we need SOMETHING to
compile native w32 code, such as setup.exe -- and gcc3 is getting long
in the tooth. (Alternatively, we could "let a thousand flowers bloom"
and have all three: mingw64-gcc-32bit, mingw64-gcc-64bit, and
mingw-gcc-32bit cross compile toolchains in the distro...and cgf was
worried about confusion?)
Preferably, I would like to see all 3 of them available for Cygwin.
They shouldn't conflict either, they have different target triplets.
