The ada entry is afflicted too (it's supposed to match the second part
of its compilation.txt, its first part is matched by the gnu pattern).
So,

	* progmodes/compile.el (compilation-error-regexp-alist-alist):
	In ada, aix, ftnchek, mips-1, mips-2, perl, sun, 4bsd entries add ".*"
	so as to match in the middle of a line, now that there's a "^" anchor
	is again enforced by compilation-mode-font-lock-keywords.  These
	patterns were otherwise failing to match anything at all.
	In the 4bsd entry remove the "^" from inside the \\(\\) grouping since
	it's now unnecessary and since inside a group it isn't recognised by
	the omake indentation hack in compilation-mode-font-lock-keywords
	(meaning it wouldn't work with indentation).
