Pls, include stdlib.h and you'll be happy.

The C standard (call it C99, but this comes from the earlier days) states
that void * is implicitly casted to everything is on the other side.

By explicitly casting malloc() you don't get the warning you wrote, but
the correct way to vanish the warning is to include stdlib.h.
