[PATCH] mountlist: fix local drive detection on cygwin |
Date: |
Tue, 28 Dec 2010 10:46:05 -0700 |
* lib/mountlist.c (ME_REMOTE) [__CYGWIN__]: Provide implementation
that works for cygwin.
Signed-off-by: Eric Blake <address@hidden>

Any objections to applying this patch? I used it when building
the official cygwin port of coreutils 8.8. In cygwin's getmntent()
implementation, all mount points are mapped to a windows-style
path (but using / instead of \), therefore, even local disks begin
with a drive letter, and are rejected by the default ME_REMOTE.
