HEAD
replced tester.fs and coretest.fs with the new versions from John Hayes
make mostlyclean virtualclean added
Cache-flushing now works on the Alpha (other minor changes there)
configure now uses gcc by default and passes its GCC variable to the Makefile
introduced sourcefilename and sourceline# (and used them in many places).

9: dnl differences in what is obtained from gcc and from the default cc.

33: [ --with-debug specifies option -g to compile with debug info (default)
