>From sources supped yesterday (20 April), I keep getting the following
   error when trying to build xinstall:
   
      cc -O -Werror -c xinstall.c
      cc: Internal compiler error: program cc1 got fatal signal 6
   
   Any ideas on what this means and how to fix it?

it means you need to rebuild gcc first.  you can fix it by rebuilding
and reinstalling gcc.
