Lenz,
thanks a lot for your answers. I have a few more questions, then:

Oh, I haden't noticed the --enable-assembler (and I have very little
experience with installing from source) so this would of course explain
something.
However, I had planned to do my experiments with C code (I haven't got
the slightest idea about how to do assembler, and the Altivec C
extensions map nearly one-to-one to the Altivec assembler instructions
anyway), so I would need to mingle with the C versions.
There, I have seen that there is a flag HAVE_STRSTR (and the like) which
seem to exclude the code. I guess it means that these versions are only
used if the underlying OS/stdlib does not provide them. Is that right -
and if so what would be the "correct" way of building? The Altivec code
would of course have to be #IFDEF'ed somehow to protect other platforms.
I take it from your answer that these are actually the routines used in
queries such as " x LIKE '%blah%', and it would make sense to attack
them?
Thanks again for any info,
Morten
Oh, and I forgot: "database,sql,query,table,handler,compile,ChangeSet"
