;; Notes on xbuild and devenv commonalities
;;
;; These regexes were tailored for xbuild, but apart from the concurrent
;; build-marker ("1>") they share exactly the same match-markers.
;;
;; If we don't exclude the match-markers explicitly, these regexes
;; will also be used to match for devenv as well, including the build-marker
;; in the file-name, causing the lookup to fail.
;;
;; So if we don't want devenv to fail, we actually need to handle it in our
;; xbuild-regexes, but then we automatically get devenv-support for free.
