The only thing preventing me from using Go on Windows is lack of production quality cgo on Windows x86 and x64.
For example, using external linking should "just work" with recent versions of sqlite3 but it fails on Windows.
I had no problems building go-sqlite3[1] on Windows 7 x64 using the toolchain provided by the Win-Builds project[2]. It's using gcc 4.8 and sqlite 3.10, so maybe that doesn't hit your meaning of "recent versions". It was certainly recent and easy enough for my needs :)
