Just because it allows you to does not mean it is strictly conforming.  It
is bad ANSI C to not #include the appropriate system headers when using
standard library calls.

For more complicated functions, you will start to get all kinds of weird
warnings based on the fact that the compiler, not knowing the prototypes
for the functions you're using, makes incorrect assumptions.

In fact there are several compilers (one of them was Turbo C) which will
start to have severe problems which are very hard to find if you use
malloc/free and forged to #include <stdlib.h>.
