Open Source != Linux
As an author of a few open source projects for 32-bit windows platforms, it sometimes bugs me to see the "it ain't linux, so it must suck" attitude present in some posts. I firmly believe in free software, and so I ensure that my projects always compile using freely available tools -- they'll still compile in commercial tools as well, but the supplied makefiles are always written for the GCC ports (mingw32/cygwin). I would welcome the inclusion of non-linux software on Freshmeat, but it might make sense to make the selection configurable, ie. by platform, license, category and so on.
