This change causes compile error in FreeBSD system.
Compiler cannot find pid_t.

I guess
===
#ifdef HAVE_SYS_TYPES_H
#include <sys/types.h>
#endif
#ifdef HAVE_UNISTD_H
#include <unistd.h>
#endif
===
is necessary for the source which includes "process.h."
I applied avobe change to xdisp.c and print.c,
and this problem was solved.
