| So in fact, you can bootstrap, but we still have problems with XEmacs right?

*X*Emacs?  could you be thinking of something different?  I saw a thread
about an abort with XEmacs.  This is a segfault that happens during the
make process for *FSF* emacs-20.2 (and 20.2.99) when the just-created
emacs executable is run like this:

  ../src/emacs -batch --no-init-file --no-site-file --multibyte ...

I bootstrapped the head of egcs-1.1 after the last change and installed it.
I cannot build a working FSF emacs 20.2 using that compiler.

  Reading specs from \
    /p/p/egcs-980817-00h35/lib/gcc-lib/i386-pc-solaris2.5.1/egcs-2.91.54/specs
  gcc version egcs-2.91.54 19980816 (gcc2 ss-980609 experimental)

Note that compiling and linking go just fine.
David Miller hypothesized that the failure is related to the unexec.
