next-error ignore info and warning levels

[Sam Halliday]

Hi all,

I would like to customise the behaviour of next-error (or, at least replace the 
keybinding with an alternative function) that skips out the info and warning 
level matches (as correctly discovered by compilation-error-regexp-alist).

Does anybody on the list have such a custom setup, or is able to advise on how 
to create the customisation?

Best regards,
Sam
