[flext] Building Flext on Windows... anyone got it working?

[Cárthach Ó Nuanáin]

Hey Jamie,

Just so you know, those were the changes I made to get flext working on
Windows with mingw a while back, in this commit:

https://github.com/grrrr/flext/commit/793392df98444adef99596d4b5e895efae9e546b

Are you on the latest commit?
