--------------------------+------------------------
 The recent update to libdeflate @1.20 fails on x86_64 builders for 10.7,
 10.8, 10.9, 10.10.  These all catch this newly added upstream error:
 {{{
 #  if !CLANG_PREREQ(3, 9, 8000000)
 #    error "clang versions older than 3.9 are no longer supported"
 #  endif
 }}}
 Which is not consistent with the four build configurations:
 {{{
 -- The C compiler identification is AppleClang 4.2.0.4250028
 -- The C compiler identification is AppleClang 5.1.0.5030040
 -- The C compiler identification is AppleClang 6.0.0.6000057
 -- The C compiler identification is AppleClang 7.0.2.7000181
 }}}
