Taking another stab at travis-ci.
Have travis actually run the tests.
Try gnu99

It seems strdup actually isn't part of the c99 standard.
_POSIX_SOURCE
Clar needs this.
Make gnu99 for the tests?
_GNU_SOURCE
Back to c99 mode.
Removing _POSIX_SOURCE from project Makefile.
Try with gcc.
Appease the linker
Weird
LIBS_posix is a thing?
Order matters
Grr, this is ridiculous.
That's not valid.
Add linker flags after pre-reqs.
See if we can build csgtool before the tests.
Move libs to the end of cc stanza
Back to make test as our target.
