FILE) if it's not a marker. The conversion to using a string containing an
expanded file name was never finished, and anyway it utterly broke
compilation-search-path and few other things.
(next-error): Expect them that way.
(compilation-parse-errors): Make them that way.
(compile-file-of-error): Function removed.
(compilation-error-filedata, compilation-error-filedata-file-name): New
defsubsts.
(compilation-next-file): Use them instead of compile-file-of-error.
generated a marker for the source position of an error message,
store (FILENAME . LINE-NUMBER), not ((DIRECTORY . FILE)
LINE-NUMBER). Doc fix.
(next-error, compilation-parse-errors): Adjusted appropriately.
(compilation-minor-mode): New defvar.
(compilation-minor-mode-map): New defvar; keymap with the bindings
from compilation-mode-map except SPC and DEL.
(compilation-mode-map): Construct this keymap to inherit from
compilation-minor-mode-map.
(compilation-setup): New function, code broken out of compilation-mode.
(compilation-mode): Call it.
(compilation-minor-mode): New function to toggle
compilation-minor-mode; if setting it, call compilation-setup.
GNU format regexp: just allowing blanks to terminate the line number
makes that one handle the HP case. Merged MIPS RISC CC regexp with
Apollo cc regexp: make "s optional, and don't anchor to bol.
compilation-directory-stack to nil; no need to loop through it.
(next-error): For a non-numeric prefix arg, pass nil for
compile-reinitialize-errors's FIND-AT-LEAST arg.
(next-error): When getting marker for error source location, be
sure to examine buffer local value of compilation-old-error-list
before switching to source file buffer.
BSD/GNU regexp to insist that line number end with a colon or
close-paren.
* compile.el (compilation-error-regexp-alist): Add regexp for the
MIPS CC distributed with Ultrix.
looking-at call doesn't clobber its value when we want to use it to back up
before the error we discard.
Make sure compilation-error-list is at least two elts long before checking
its first two elts for being in the same file.
