dnl ######################################################################
dnl Find name of mount table file, and define it as MNTTAB_FILE_NAME
dnl
dnl Solaris defines MNTTAB as /etc/mnttab, the file where /sbin/mount
dnl stores its cache of mounted filesystems. But under SunOS, the same
dnl macro MNTTAB, is defined as the _source_ of filesystems to mount, and
dnl is set to /etc/fstab. That is why I have to first check out
dnl if MOUNTED exists, and if not, check for the MNTTAB macro.
dnl
