Dan's already replied with the general details and praise for Raptor :)  

So I'll fill in some other bits.  It builds on everything I've tried
that can do standard C (linux, unixes, win32, cygwin, OSX,
cross-compiled,  ...). 

License: It's dual LGPL/MPL, so you should be able to use either of
those dynamically linked or statically with MIT-licensed.  Other
license options are possible.   The FAQs covers this more in

As for efficiency, I still claim no memory leaks and this week I got
it to parse a file with 550,000 triples in 7 seconds on a desktop PC,
using <1M of memory.

Repat was one of the better earlier C parsers.  It hasn't kept up
with some of the newer changes to the syntax.  I recommend Raptor :)
