Could not generate GMC documentation.
Due to installations of DocBook being very different across platforms
and distributions, this "mkhtml" script has been designed to run on
RedHat Linux 7.1 only. You may want to adapt it to your system if you
have DocBook 4.1 installed.

Please DO NOT make official releases of GNU Midnight Commander on the
systems where the GMC documentation fails to be generated.
