Re: [Solved] Re: emacs (cvs) doesn't build

[Richard Stallman]

    I couldn't believe it but  emacs seems to be the first package
    which fails when compiled with -O3 under gcc-3.4.3

This could be a GCC bug, or it could be an Emacs bug.
Either way, it would be quite useful to debug it.

A first step is to compile some files with -O and some with -O3.  By
trying that in different ways, you can find out which file the problem
is in.  I would suggest binary search: first try compiling half
the files with -O3, then you'll know it's in one set of half the files.
Then divide thst set in half, etc.
