 In the previous legacy-support-devel, since v1.2.4:

   Re: https://trac.macports.org/ticket/69878

 - Moves renameat() prototype to the proper header location.

 - Fixes incorrect CLOCK_UPTIME_RAW_APPROX definition

 - Eliminates spurious fmemopen() in OSes that don't need it

 - Adds appropriate __DARWIN_C_LEVEL conditionals, as in SDK headers.
   Re: https://trac.macports.org/ticket/69688

 - Reworks headers for "mismatched" SDK compatibility.
   Re: https://trac.macports.org/ticket/69867

 - Makes clockid_t an enum, matching SDK behavior.

 TESTED:
 Tested both normal and -devel versions on 10.4-10.5 ppc, 10.5-10.6 ppc
 (i386 Rosetta), 10.4-10.6 i386, 10.4-12.x x86_64, and 11.x-14.x arm64.
 Builds on all tested platforms except 10.4 ppc +universal.
 Passes all tests in all buildable cases.
