ecpg grammar in CVS is annoying

Hi,

Is it only me, or having the generated ecpg grammar is a bit obnoxious?
I am getting troubled because whenever I touch gram.y it gets updated
when I run make, and then it shows in "cvs diff".

I'm not sure what's the solution -- maybe something is missing in a
.cvsignore file somewhere?

Oh, another thing -- ecpg has a dependency on libpq, but it is not
declared in Makefiles, so if you build ecpg without first building
libpq, it errors out.
