So I've heard.  Unfortunately, there's not a lot I can do about this directly.
I'll browse the egcs list archives and see if anybody has mentioned this.  For
all I know, this is a feature, not a bug.  :-P

I've just now uploaded the new egcs package, which provides our standard
gcc/g77 compilers.  Remember that gcc 2.8.0 is the second-class citizen now;
take that into account when making a new experimental package.  You'll have to
rename the binaries in /usr/bin (gcc28 perhaps?) and set the /etc/alternatives
priority lower than 20.  (Take note of bug #17468.)

The m68k people would probably lynch me.  I don't see much value in building
the stage 3 compiler; and since the right things happen even without an
explicit "make bootstrap" (f771 and libstdc++ are both compiled with the
just-built gcc rather than the system gcc) I won't double the build time by
doing so.

Since I don't have (and have no intention of installing) dejagnus on my system,
I couldn't test any "test" target I added to debian/rules.  If you want to run
the test, just cd to builddir and type "make test" or whatever.  Is that really
so hard?
