Leon sent me some updates on his grant:
I've been less productive than previous period this time, mainly due to school obligations. I've improved the Build system and the file layout. I've added some tests for regular expressions, which uncovered a number of bugs that seem to be fixed by now. Unless I uncover more bugs (not expecting them), the regexps are finished. I've also done some testing on windows, with limited success. Strawberry ships with a rather old compiler (gcc 3.4.5), which refused to compile my code, I hope I can get Curtis to update the gcc. Testing with MSVC is the next goal.
