bec236c108 Include more headers to declare functions. 
This causes clang to give fewer warnings of implicit declarations of
functions.

In mach/pdp/cv/cv.c, rename wr_int2() to cv_int2() because it
conflicts with wr_int2() in <object.h>.

In util/ack, rename F_OK to F_TRANSFORM because it conflicts with F_OK
for access() in <unistd.h>.

84f65f7ce3 Raise _XOPEN_SOURCE from 500 to 700 
In OpenBSD, _XOPEN_SOURCE 500 forces _POSIX_C_SOURCE down to 199506,
which hides the declarations of openat() and fdopendir() and causes
compiler warnings.

Don't set _POSIX_C_SOURCE, because _XOPEN_SOURCE may set
_POSIX_C_SOURCE to a different value.

79a38ecc08 Instead of using parameterised rsts for stack access, add a huge swathe of 
automatically built helper tools. Star Trek goes up from 40243 to 40779 bytes,
but should be a lot faster.

698613cd7d Turns out that the compiler needs access to the libpc headers too; refactor 
into a separate target to avoid build loops and make it work.
