No, I disagree. The function declarator can be arbitrarily long, sometimes
wrapping over several lines on the screen. If the important "matches no
declaration" text is at an arbitrary place on the screen it is hard to find=
. If
it appears immediately after the "error:" string (which is typically
highlighted in red) then you don't have to scan the output to find it.

"X matches no declaration" also seems grammatically worse than "no declarat=
ion
matches X", but that's debatable.=
