* INSTALL: Rebuilt.

        * install.texi: Remove "Object File Differences" section.  Remove
        all references to zzz.o failing comparison tests.
        * version.c, version.h: Renamed from zzz.c and zzz.h.  Remove
        date and time stamps so a 3 stage build reports no differences.
        * Make-lang.in: Corresponding changes.
        * Makefile.in: Likewise.
        * g77.c, parse.c: Likewise.
So 3-stage build compares OK.  Rename zzz.[ch] files to version.[ch].

-Object File Differences
-.......................
-
-   A comparison of object files after building Stage 3 during a
-bootstrap build will result in `gcc/f/zzz.o' being flagged as different
-from the Stage 2 version.  That is because it contains a string with an
-expansion of the `__TIME__' macro, which expands to the current time of
-day.  It is nothing to worry about, since `gcc/f/zzz.c' doesn't contain
-any actual code.  It does allow you to override its use of `__DATE__'
-and `__TIME__' by defining macros for the compilation--see the source
-code for details.
