Not sure where to go for that. The problem is really in Emacs's hacky 
implementation: when 'omake' is included in compilation-error-regexp-alist, 
many other regexps are rewritten in a way that makes them potentially slower. 
This is why it's not an ideal feature to have enabled by default.

Attached are two patches: one that anchors the regexp for Maven, and one that 
speeds up 'msft' and 'watcom' by eliminating the same 
repetition-after-repetition flaw in each (not much different from those found 
by the latest relint/xr scan posted to emacs-devel).
