On 19 March, 2003, I posted a note:
Emacs M-x gdb does not correlate CYGWIN symlinks to source files to
cygwin@cygwin.com.


The suggestion was, "use CYGWIN Emacs".  (I tried it but stayed with Gnu.)

I just tried this once more, but in a very simple environment (no symbolic
links of any kind).

When a break triggers in "test.c", Emacs opens a buffer, "test.c<2>" on
mythical file
"c:/cygwin/c/...test.c".  It appears that Emacs helpfully added the missing
drive letter.

I suggest that if Emacs did not add the drive letter when the /cygdrive
notation is present
(on a system with CYGWIN installed), then Gnu Emacs, CYGWIN and gdb would
all play
together straight out of the box.

(Of course, I could just be doing something horribly wrong, since I cannot
imagine that I
am the first to tread this path and, no, I can't really believe this doesn't
work.)

Cheers,
Keith
