Hello,

Without NATIVECOMP, emacs-devel@nox fails to build on a poudriere jail version
15.0-CURRENT 1500020, with this error:


timespec-sub.c:38:12: error: operand argument to checked integer operation must
be an integer type other than plain 'char', 'bool', bit-precise, or an
enumeration ('bool' invalid)
   38 |   if (v == ckd_sub (&rs, rs, borrow))
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~
/usr/include/stdckdint.h:24:37: note: expanded from macro 'ckd_sub'

      |                                            ^~~
1 error generated.


This simple patch allows the build to succeed.
