Cross-compiling using mingw32 not working

[claesenm]

./configure --host=i686-w64-mingw32
make

leads to errors in the LibSVM wrapper, related to malloc:

src/LibSVM.cpp:43:32: error: 'rpl_malloc' is not a member of 'std'

This appears to be because of a directive in configure.ac, based on http://nerdland.net/unstumping-the-internet/malloc-has-not-been-declared/

[claesenm]

Problem disappears when removing the following lines from configure.ac, though this is not a fix:

AC_FUNC_MALLOC
AC_FUNC_REALLOC

merge-models -model1 a9a.ensemble -model2 a9a.pred.ensmeble -o six.ensmeble

when merging two models created using esvm, the models could not be merged. Segmentation fault(core dumped)..

How to solve this issue??
