* new fnmatch implementationRich Felker2012-04-281-131/+273
| | | | | | | | | | unlike the old one, this one's algorithm does not suffer from potential stack overflow issues or pathologically bad performance on certain patterns. instead of backtracking, it uses a matching algorithm which I have not seen before (unsure whether I invented or re-invented it) that runs in O(1) space and O(nm) time. it may be possible to improve the time to O(n), but not without significantly greater complexity.
* update fnmatch to POSIX 2008 semanticsRich Felker2012-04-261-4/+11
| | | | | | | an invalid bracket expression must be treated as if the opening bracket were just a literal character. this is to fix a bug whereby POSIX left the behavior of the "[" shell command undefined due to it being an invalid bracket expression.
* eliminate (harmless in this case) vla usage in fnmatch.cRich Felker2011-06-051-1/+1
