[MPlayer-users] Small improvement for configure (0.90pre2)

[Gregor Hoffleit]

A small annoyance with the configure script is that it hardcodes the
full path of DATADIR, CONFDIR and LIBDIR into the config.mak file (i.e.
it expands $prefix).

The result is that things like "./configure; make install
prefix=/usr/local/stow/mplayer" won't work: Most of the stuff will be
installed in /usr/local/stow/mplayer, but the makefiles that use DATADIR
or LIBDIR to *install* things (e.g. vidix/drivers/Makefile) will
nevertheless try to install in /usr/local. That makes it impossible to
use tools like "stow".

AFAICS, a fix would be to change the configure script so that it sets
DATADIR, CONFDIR and LIBDIR in config.make to the unexpanded values, and
in config.h to the expanded values.

Thanks,
