That bug seems to be about adding filtering based on exception type, not 
about supporting catchpoints in general; the latter have worked for 
years in gdb-linux (at a minimum, my server at work can do it with 
gdb-7.4).

The problem here is that gdb-cygwin crashes when running with a 
catchpoint enabled. I don't see any bugs on Sourceware about that, 
though I suspect the search interface is terrible so I could be missing 
something obvious.
