And so does DEC C on openVMS/Alpha. A patch for this was submitted by me
last year, I wonder where it went ...

This doesn't work for DEC C on openVMS/Alpha since digital put the prototype
in <stdlib.h>. So I'd supposed adding

#ifdef HAVE_STDLIB_H
# include <stdlib.h>
#endif

would help a lot on VMS and shouldn't harm other systems.
