This problem is much smaller than it may appear.  The full wildmat 
syntax is nearly identical to the Unix fnmatch function, for which there 
are multiple freely available implementations with locale support 
already plumbed in. There are a few small differences between wildmat 
and fnmatch like ^ vs. ! for negation, but the code can be copied nearly 
verbatim.
