On systems where 'mode_t' is smaller than 'int', doing 'va_arg (ap, mode_t)' is
wrong because of C's "default argument promotions". GCC 4 creates crashing code
in this case.
The "va_arg" page of Gnulib's manual describes the problem and a simple solution:
https://www.gnu.org/software/gnulib/manual/html_node/va_005farg.html
However, since that solution reportedly (see thread at next link) still causes
GCC to print warnings (for no good reason; perhaps this was fixed in newer
GCCs), we pick a solution that defines a PROMOTED_MODE_T at the configuration
stage:
https://lists.gnu.org/archive/html/bug-gnulib/2009-05/msg00231.html
(We take our 'mode_t.m4' from the most recent Gnulib source.)
(If any of the URLs above no longer works, simply search the web for the
mentioned words.)
Use real errno or set it to 0 when no meaningful error code exists
for current user error message.

Introduce -Wswitch-default check.
Some minor cosmetics.

If you navigate in your shell to a directory containing symlinks and
then start mc, mc will show the canonical path instead. It would be nice
to make it show the directory with the symlinks.
Example: in your shell execute these:
user:~$ mkdir -p /tmp/a/b /tmp/x ; ln -s /tmp/a/b /tmp/x/y
user:~$ cd /tmp/x/y
user:/tmp/x/y$ mc
In mc you'll find yourself in /tmp/a/b, though it'd be nicer to see
/tmp/x/y at the top, and correspondingly navigating to the parent would
take you to /tmp/x.
If you start bash or zsh from /tmp/x/y, the new instance will start
displaying the working directory as such. They do this via the PWD env
variable. On one hand, they set and maintain PWD to point to the current
directory, using the path as specified by the user (possibly containing
symbolic links). On the other hand, they check its value at startup. If
$PWD points to the same physical directory as the actual working
directory then they use this value. If $PWD points somewhere else then
it's simply ignored (so it's a hint only as to which symlinks to use to
get to the working directory, but never alters the actual cwd).
Now mc also does the same at startup (with respect of "Cd follows
links" option). Relative directories specified in the command line are
applied after possibly replacing the canonical cwd with $PWD. This way
for example
user:/tmp/x/y$ mc . ..
opens two panels in /tmp/x/y and /tmp/x instead of /tmp/a/b and /tmp/a
(whereas /tmp/x is actually a different directory than /tmp/a).
