-- Non-Win32: build using the Makefile
-- Win32: build using 'make-vc.cmd' and "manual" copy of products
--
-- TBD: How is MSYS treated?  We'd like (really) it to use the Makefile.
--      It should be a target like "cygwin", not defining "windows". 
--      "windows" should actually guarantee Visual C++ as the compiler.
--
-- Q: Does "win32" guarantee we have Visual C++ 2005/2008 command line tools?
--
-- Note: Cannot use the simple "module" build type, because we need to precompile
--       'src/keeper.lua' -> keeper.lch and bake it into lanes.c.
