BREW uses RVCT or GCC for target. So malloc, calloc, realloc and free are
provided by these two compilers. However, because BREW runtime does not
initialize the heap for application, calling malloc crashes the system. To
share system heap, BREW applications must use MALLOC, CALLOC, REALLOC and FREE.

Naming the function malloc causes a compile error if stdlib.h is included.

void* malloc(size_t)' was declared `extern' and later `static' error.

I think it is a good idea.

One simple approach is to replace malloc, calloc, realloc and free with their
corresponding counterparts MALLOC, CALLOC, REALLOC and FREE using macros.
