It does seem that there is a debate -- but I'm not part of it. My only
involvement with either the last few days is fixing cygport for
cross-compilers and cross-compiling.
That being said, I see the technical arguments for allowing both
toolchains (provided someone steps up and packages a mingw.org version).
Mingw.org-based software is still widespread, and as JonY mentioned they
are not fully compatible. OTOH mingw-w64, besided providing the only
64bit option, also has certain advantages which warrant a 32bit version
Here's my question, though: given the incompatibilities mentioned, would
a cygwin1.dll built with i686-w64-cygwin (mingw-w64) toolchain be 100%
compatible with current and past releases built with i686-pc-cygwin
(mingw.org) toolchain? If not, then we need both.
