On a lark (and to get waitpid()), I tried building perl in my
compiler's ANSI mode. Unfortunately, in doio.c there are a bunch of
calls accessing the statbuf fields with & operators. The problem is
that in strictly conforming ANSI mode, those aren't defined -- you must
use them as macros. The relevant portions of <sys/stat.h> are included
below.
Remember: standards are your *friends*. :-)
