M-x occur ^[^!C-qC-j]*regexp
ought to work (the C-qC-j bit gives you a newline).
It will be fooled by instances of your desired regexp occurring after
a string containing !, but I imagine that's unlikely. If you needed
to deal with that, you could cook up some elisp using f90-in-comment.

I guess comp.unix.shell or somesuch place is the right place for grep
questions.
