POSIX defines pid_t in sys/types.h
(https://pubs.opengroup.org/onlinepubs/009604499/basedefs/sys/types.h.html)
But the way AC_TYPE_PID_T works, is pid_t if incldued in the standard
ac_includes don't define it.
standard includes in the version of autoconf that is currently used are:
```
#ifdef HAVE_SYS_TYPES_H
# include <sys/types.h>
#endif
....
#ifdef HAVE_UNISTD_H
# include <unistd.h>
#endif"
```
Looks like vms defines it in unistd.h from what I could find on the internet.
So confirmed. Though I am not 100% sure if building for VMS is still supported.
