googled a bit and found swift solution:

Modify the /mingw/lib/gcc/GCC-VERSION/mingw32/include/float.h file and add

#ifndef _MINGW_FLOAT_H_
#include_next <float.h>
#endif

(yeah, literally copy and paste at the end of that file)

Read here: http://sourceforge.net/mailarchive/message.php?msg_id=28824347

i wonder how to workaround this w/o modifying the file...
