Re: make bootstrap fails

[Richard Stallman]

We should certainly delete all the cc-bytecomp-defun stuff.  It is an
ugly approach.  However, that code has worked for years, and it has
not been changed, so this must imply a compiler bug somewhere else.
We should investigate that and fix it before deleting
cc-bytecomp-defun.

I was unable to make this fail by recompiling cc-bytecomp and cc-vars.
I can't afford to do a bootstrap--too many meetings today.  But if you
byte-compile-debug to t, you should be able to get a backtrace.  Very
likely investigating that backtrace will make considerable progress.
