when gcc (and clang) moved to target C99 by default (after version 5)
then that wall of errors went away.  Indeed git can build cleanly in a
strict C99 compiler and until reftable was able to build even with gcc
2.95.3

the nostalgic can get it back with `CC=gcc -std=gnu89`, and indeed I
was considering this might be a good alternative to the defunct
gcc-4.8 job, where the weather balloons breaking with strict C89
compatibility could be explicitly coded.

agree, and indeed was thinking it might be worth combining this job
with the SANITIZE one for efficiency.
