First, do not ever, ever send such a big file on a mailing list again.
I for one don't care, as I have broadband access, but there may be
people that are behind dial-up, and that can't afford the bandwidth
for such a file. Pfeww. 8.5 MiB! At least, compress the file, nest time,
please...

Looks like an issue with gcc being unable to link with static ppl. This is
a known issue. There is a patch pending, but unfortiunately, it is not
available in the archives (due to an incorrect CC field when submitted).

The attached patch is absolutely untested, and is definitely _not_ the
proper fix, but if you confirm that it fixes the issue on your side,
then I can come with a proper fix. The patch applies to current head
of the repository, and may not apply to 1.7.x. Care to test and submit
the result, please?

Yann E. MORIN.
