Change all the POSTINSTALL 'mkfontdir' to 'mkfontdir -x .lev' although
the mkfontdir version on my system didn't think $(HACKDIR)/*.lev were
font files when I built without dlb.
Also change the PREINSTALL 'cp -n win/X11/nethack.rc ~/.nethackrc' to
keep going if it fails. The linux hints use 'cp -n' for sysconf but
since it is doing so for the playground directory and 'make install'
starts out by clearing away everything in that directory, it shouldn't
fail. But some extra bullet proofing there may be warranted. Only
the initial cp is protected against clobbering an existing file; the
ownership+permission fixups that are applied to the copy of original
file still get applied to an existing one.
Separate the compiler flags used for compiling X11 code from the rest
of CFLAGS. Affects hints/macosx10.8 and later.
Add an explicit output argument to the generated compile rules.
The change to Makefile.src for X11+XPM on linux broke linking X11 on
OSX. This updates the hints files (except for the -qt one) so that
make WANT_WIN_X11=1
and
make WANT_WIN_X11=1 USE_XPM=1
work correctly.
The comment in macosx10.14 about what version(s) it's intended for
and been tested on is just cloned from 10.10 and should be updated.
