I am using
GNU Emacs 22.1.1 (i386-mingw-nt5.1.2600) of 2007-06-02 on RELEASE
Windowing system distributor `Microsoft Corp.', version 5.1.2600
configured using `configure --with-gcc (3.4) --cflags -Ic:/gnuwin32/include'
I have `shell-file-name' set to "bash" and I type M-x compile RET make RET.
Cygwin's "make" produces the following output in the *compilation* buffer:
----------------------------------------------------------------------------
-*- mode: compilation; default-directory: "c:/tmp/test/" -*-
Compilation started at Fri Apr 25 13:13:20
make
make -f src/Makefile
make[1]: Entering directory `/cygdrive/c/tmp/test'
gcc -Wall -g -o build/test.o -c src/test.c
src/test.c:1:2: #error Error
make[1]: *** [build/test.o] Error 1
make[1]: Leaving directory `/cygdrive/c/tmp/test'
make: *** [all] Error 2
Compilation exited abnormally with code 2 at Fri Apr 25 13:13:21
----------------------------------------------------------------------------
Now I type M-x next-error RET. I expect Emacs to go to the location of
the first error, but instead it asks me thiis question:
Find this error in (default src/test.c): c:/cygdrive/c/tmp/test
The reason it can't find the file is that
`compilation-directory-matcher' has matched the recursive make's
"Entering directory" line, which contains an absolute path name in
Cygwin syntax; and then `compilation-find-file' has called
`expand-file-name', which has converted `/cygdrive/c/tmp/test' into the
incorrect `c:/cygdrive/c/tmp/test' instead of the correct `c:/tmp/test'.
I am aware that I can work around this problem by advising
`expand-file-name' to recognize Cygwin path names and convert them to
path names that Emacs recognizes, for example like this:
(defadvice expand-file-name (before cygpath-convert-to-emacs-path activate)
(let ((name (ad-get-arg 0)))
(when (string-match "^/cygdrive/\\([a-z]\\)\\(/.*\\)" name)
(ad-set-arg 0 (concat (match-string 1 name) ":" (match-string 2
name))))))
However, it would be nice if recursive make in Cygwin worked in Emacs
out of the box.

You probably want to use cygwin-mount.el. I always thought it would be
a nice addition to Emacs, but people more knowledgeable about Windows
seemed to be rather opposed to it last time this popped up.

It does, if you use the Cygwin build of Emacs.

FWIW - I'm not knowledgeable about Windows, but I use Windows, and I too think
it should be added to Emacs. Or at least made more obvious to Windows users.

That's very helpful, thank you.
(And now I've learned about `file-name-handler-alist' too.)
