In the current CVS maxima sources, *maxima-directory* is hardwired to
a fixed path. However, in the CVS sources from U Texas,
*maxima-directory* used to be set (in set_pathnames) to the value of
the environment variable "MAXIMA_DIRECTORY". Should we do this?
Or is configure expected to set *maxima-directory* to be the
installation directory?
Maybe we should do both so configure sets the initial value but allow
the user to override it with the environment variable?
