Personally, the only thing I use Windows for is to fire up a 64-bit MinGW environment and build/test jemalloc. I spent several days leading up to the 4.0.0 release making the test suite run and pass, but my lack of familiarity with modern Windows makes pretty much every experience with it intensely frustrating, and I keep hoping that others more familiar with Windows will round off the rough edges and document build procedures. I've heard of people working around configuration issues to successfully build using Cygwin, and I'm pretty sure Mozilla uses MSVC with jemalloc.
