Build failure on the 13.1 based source due to "unused variables"

[a_ba...@ymail.com]

I'm attempting to build from source and when getting to the kern_procctl.c file I keep getting unused variables error.  I've pasted the output below.  I've attempted removing the #ifndef PAX lines to see if maybe the "vm" variable, and the others, were being excluded and that would be why they were being marked as unused.  I have also gone onto the FreeBSD forums to see if I could find a fix to the issue there to no avail.

Any suggestions would be greatly appreciated.  Been at this for two days before coming here.  I prefer to try to fix something before asking for help.

This is the error output:
