added
#mode standard Prolog
to several files. The problem is that sometimes these files (eg syslib/flrtables.P)
would have to be recompiled while compiling a .flr file (eg, due to a timestamp screwup). In that case, flrtables.P would be preprocessed with the -F option instead of the -P option, which can cause problems. For instance, comments and escape conventions are different in Flora and Prolog.
So, putting #mode standard Prolog in the key files ensures that these files are preprocessed in the Prolog mode.
