This has been giving me headaches for days already.
stdlib.h is included by this file and the warning I placed directly underneath the declaration of malloc was displayed as well, but somehow (see mingw) are malloc and realloc undeclared again. When compiling natively on Linux nothing like this happens and I have trouble understanding what's going on.

Anyone an idea?

No, not the remotest idea, just a very dirty, despaired workaround and a link...

Thanks a lot, this did the trick, I finally got to see the errors I was actually looking for (linking errors) and can now finally start (to try) to fix the last show-stoppers before 2.2.0.
(linking errors + crash at statistics page on Mac)

A fix is already in svn. However, the real "fix" would be not to use malloc()/realloc() at all.
