Patches are welcome.

Maybe, but it's not simple, because there's more than one kind
available out there.  I have 3 on my system, and they report,
respectively:

  MINGW32_NT-5.1 HOME-C4E4A596F7 1.0.17(0.48/3/2) 2011-04-24 23:39 i686 Msys
  MINGW32_NT-5.1 HOME-C4E4A596F7 1.0.12(0.46/3/2) 2012-07-05 14:56 i686 unknown
  windows32 home-c4e4a596f7 2.5.1 2600 i686-pc Intel unknown MinGW

In a nutshell, most of what a ported 'uname' reports is hard-wired
into it when it is built, because there's no such OS as "MinGW".
That's hardly a good way of reliably identifying MinGW.
