Hello,
with mingw-w64 (i686-w64-mingw32 4.7.0 rubenv and 4.6.3 from strawberry
perl 5.16.0.1 win32) some patches are necessary.
./configure --enable-debug --enable-fill fails in configure with:
error: cannot determine value for STATIC_PAGE_SHIFT
It builds and passes make check after saving the following patches
in to a file in the build directory. If the patches are in fix.patch,
then patch -p1 < fix.patch applies the necessary patches.
Kind regards,
Kai-Uwe Eckhardt
