[Ecls-list] Release candidate for ECL 12.2.1

[Juan Jose Garcia-Ripoll]

ECL builds fine on all supported platforms, but there are two types
of issues with Windows:

* Mingw32's latest compiler, gcc-4.6.2, miscompiles several files and
  breaks down while building ECL. This is not due to wrong C code but
  a problem in that version of GCC. The solution is to install an
  older version of GCC. It suffices with gcc-core, g++ and libgcc

http://sourceforge.net/projects/mingw/files/MinGW/Base/gcc/Version4/gcc-4.5.2-1/

* Cygwin's fork routine is very fragile. Unfortunately it is the only
  mean that ECL has to implement EXT:RUN-PROGRAM on that platform.

Accepting this, I feel that a release can be safely produced
