... and complains that gcc doesn't produce a warning.

You wouldn't be using a Sun by any chance, would you?  Perhaps a Sun
whose <stdlib.h> contains a line like this:

   extern char *   realloc(/* void *ptr, size_t size */);

Note the commenting out of the arguments.

It's not gcc's fault; just use a real prototype for realloc().
