[Openmcl-devel] Windows versions of CCL available for smoke-testing

this is exciting news. In our case we really would like the Mac32/64 +
Win32/64 Lisps but our tire kicking activity would be to try to get
OpenGL and QuickTime to work on Windows. Sounds like the win32 version
may be still to shaky for this kind of stress test? Is there a plan to
have SLIME work with win32 and will there be a precompiled .exe
version of ccl/win32? Is there already or will there be a mechanism
similar to the trap mechanism on Mac for OS X calls to parse header
files to turn them automagically into defcallbacks (or whatever they
will be called)?
