XCOMM redirect errors to a file in user's home directory if we can

errfile="$HOME/.xsession-errors"
if ( umask 077 && cp /dev/null "$errfile" 2> /dev/null )
then
	exec > "$errfile" 2>&1
else
#ifdef MKTEMP_COMMAND
	mktemp=MKTEMP_COMMAND
	for errfile in "${TMPDIR-/tmp}/xses-$USER" "/tmp/xses-$USER"
	do
		if ef="$( umask 077 && $mktemp "$errfile.XXXXXX" 2> /dev/null)"
		then
			exec > "$ef" 2>&1
			mv "$ef" "$errfile" 2> /dev/null
			break
		fi
	done
#else
XCOMM Since this system doesn't have a mktemp command to allow secure
XCOMM creation of files in shared directories, no fallback error log
XCOMM is being used.   See https://bugs.freedesktop.org/show_bug.cgi?id=5898
