My only concern about C99 is that, despite appearing to be 16 years
old, it's not.  GCC 4 still defaults to C89, you need to override the
default or use GCC 5 to get C99 by default.

The big disconnect between C89 and C99 is the difference between
"extern inline" and "static inline", GCC 4's interpretation is
different than GCC 5's, so we should avoid those constructs during the
migration.
