2020-06-21issue #8: twm displays all windows as "Untitled"Thomas E. Dickey

2019-03-03Read system.twmrc from where it got installedBryan Kadzban
${rcdir} is ${datadir}/X11/twm by default, but can be overridden when running make. If it is overridden, then the code should read from the same place as where "make rcdir=FOO install" puts the file. (Obviously overriding rcdir= for "make install" requires overriding it for "make" as well. But at least this way it's possible to get it to work. :-) ) Signed-off-by: Alan Coopersmith <alan.coopersmith@oracle.com>
