Re: Failure to build on OpenBSD macppc

[Alfred M. Szmidt]

       Ok, I have narrowed down the problem to being a problem in GCC,
       not in Emacs.  Emacs compiled with "-g -O2" (the default) does
       not work, while -O1 does.  This also explains why -ggdb3
       worked, I never passed a optimisation switch, so Emacs was
       compiled without optimisations.

   Which GCC versions does this fail with?  Does it fail with the
   latest GCC version?  If so, we had better track it down so as to
   make a good GCC bug report.

OpenBSD uses their own heavily patched version of GCC, which is quite
old (3.3.5) compared to our version (4.2.0).  For all I know, it can
be a bug that only exists in OpenBSD's GCC, and not in our GCC.

   For this Emacs release, we can deal with it with a note in
   etc/PROBLEMS.  But that note should say whether upgrading GCC is a
   solution.

I don't think this is a very important thing to mention, upgrading GCC
just to compile Emacs seems like a lot of work.  Not to mention that
GCC 4.2.0 that was just released doesn't compile on OpenBSD 4.0 (to
atleast my great suprise).
