Switch to compiling as ISO C99 + GNU extensions. (#203)

Browse Source 
We currently build for ISO C90 with GNU extensions. The GNU
extensions include both library and language features.
Compiling without GNU extensions results in a number of compilation
failures due to use of those library features.

With this, we'll build for ISO C99 with the GNU extensions and
can evaluate what's going on with those library features in the
future.
