I am not in a palce to try this out, but there was a change made by
another Developer lately to the file configure.ac that may be a problem.
Modify configure.ac and find this section of code and remove all the
lines from below:

dnl Compiling with -O3 makes a useful difference with gcc, clang and Sun's
dnl compiler ; -ffast-math helps as well when available.
dnl For instance, some match analysis on a Core i5 CPU (gcc 4.4.7, -mavx) :
dnl -O2             1:23
dnl -O3             1:14
dnl -O3 -ffast-math 1:11

if test x"$GCC" = "xyes"; then
    AX_APPEND_FLAG("-ffast-math", AM_CFLAGS)


After you remove all the lines above do:

make clean
./configure CFLAGS="-I/mingw/python27/include" --without-gtk

If this works for you let me know so that the configure.ac file can be
looked at.

Thanks, I'll correct that with the installer. I hadn't noticed it
