This now means iconv or apr-iconv are a hard global dependency where they
haven't been before. I'm not sure that I like that. (If you're going to
do this patch, remove the if check for EINVAL/ENOTIMPL - it's unnecessary.)

IIRC, the reason is that this code gets called all the time - we had to
silence the ENOTIMPL and EINVAL errors as it really shouldn't be treated as
a fatal error. So, in this case, we're back to treating it as an
irrecoverable error.

It's probably better to just check APR_HAS_XLATE and return an error in
svnsync if that's 0...and let the string pass through unmodified - which is
probably fine for svnsync case...or perhaps go a step further and just
refuse to build svnsync if iconv isn't supported as we might not be able to
guarantee the integrity of the sync'd logs. I'm not sure how paranoid we
need to be here. -- justin
