There are some minor issues with the configure stage that you want to clean up:

- checking for X... libraries /usr/lib, headers /usr/include
- checking for 
/home/schloegl/src/mxe.github.schloegl/usr/i686-pc-mingw32/bin/pcre-config... no
- configure: WARNING: You used --enable-dl but not --enable-shared.
- configure: WARNING: cURL library not found.  The ftp objects, urlread and 
urlwrite functions will be disabled.
- configure: WARNING: You used the EXPERIMENTAL --enable-openmp option.

Apart from --enable-dl, none of these are likely to be significant, but it 
doesn't hurt to remove the warnings until you get a successful build.

The vast majority of undefined references [1] seem to be c++ related (e.g. 
'std::', 'operator', '__cxa'). The above should be invoked as 
i686-pc-mingw32-g++.
