That's precisely why I'm asking this. I don't have a formal request
in yet to maintain Lua for them, but I want to be prepared to
know how much work it is and also to have a build framework
that I can live with.

That would mean fixing up a lot of the LuaRocks rockspecs...

-mno-cygwin is going away with Cygwin 1.7 - they will release a separate
build of gcc for mingw builds.

Thanks for the links David - I'll look at them carefully.

My initial desire is to build the following libraries along
with Lua:

LuaFilesystem
LuaSocket
LuaSQL

Are there other must-have libraries that are worth including in a Cygwin
Lua package?
