$ make -k CFLAGS='-O0 -g'
# this errors out in fdct_mmx.c with "operands invalid for `pshufw'"
$ rm quicktime/ffmpeg/libavcodec/i386/fdct_mmx.*o
$ make CFLAGS='-O2 -g'
(It seems that this file wants to be compiled with some different sort of
optimization.)
BTW, I just noticed that the build flags of quicktime/ffmpeg/libavcodec/i386/
include -O3. Try removing that from Makefile.am - it is needed on i*86, but
may not be needed on x86_64.

A successful build - finally...thank you Hannes.
As they say in Experts exchange or wherever - you win the prize...
I'm not clear yet on where the build was going wrong but most definitely
in the quicktime/ffmpeg/libavcodec/i386 directory.
I decided to try with the latest automake (1.10) and my eventual success
suggests the debian build comments in the autogen.sh script now need to
be deleted (they say to use automake 1.7).
Another discovery : I came across references in makefiles to previously
used automake versions. I manually purged a lot of hvirtual directory
files to overcome this. So perhaps the autogen.sh script does not clean
out all the old files properly. Some of these maybe: depcomp, libtool,
ltmain.sh, mkinstalldirs...
I started with a no flags: ./configure
then: make
once it broke I used: make -k 'O0 -g'
make (to remind me where breakages were still happening)
rm quicktime/ffmpeg/libavcodec/i386/..[broken lib].*o
fiddled with the Makefile in quicktime/ffmpeg/libavcodec/i386/
and used either
make CFLAGS='-O3 -g'
CFLAGS='-O0 -g'
or: CFLAGS='-O2 -g'
until all the build errors were solved.
My final Makefile in the i386 directory had no -O3 optimisation, no
-prefer-non-pic and included an -fPIC flag.
Until I discover exactly which steps were necessary my bug report is
probably not useful - I will only submit one if someone here tells me
it's a good idea.
Hopefully my skills will eventually allow me to make packages and submit
patches. But that could be quite a while away...
For now all I can do is say thanks everyone for all the help. I'm happy
to have my Cinelerra back!
Graham
