Actually cstdlib undefines malloc and realloc in favour of std::malloc std::realloc

Then it cant find the std:: functions.

I am having a similar problem compiling a cross gcc for uclibc with thier patches.
but with snprintf instead. ( same std::snprintf member not existing thing )

Part of my problem I have found is that gcc will ignore certain error while building - 
thus hiding the fact that they occured. (libstdc++)

I am beginning to think that I have a problem that is being passed on from my previous 
compiler. But I dont see how.

I cant even build gcc-4.0.0 without errors at the moment. - It cant find existing files.
