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
