Oups my bad, It was not the correct mingw version.

Actually I can't compile on Windows:

src/2geom/hvlinesegment.h:1: error: stray '\357' in program src/2geom/hvlinesegment.h:1: error: stray '\273' in program src/2geom/hvlinesegment.h:1: error: stray '\277' in program

I had to encode hvlinesegment.h from UTF8 to ANSI to fix this
