There is one question regarding the ABI. Apparently, the string length

is indeed the case by doing the actual work on a
powerpc64-unknown-linux-gnu box (gcc110 on the gcc compile farm),
which is big-endian. If we were actually passing an eight-byte
quantity, and only getting the upper bytes, we would crash & burn.
Now, I _thought_ we were passing string lengths as size_t now (Janne?),
but maybe something was missing in that change.
Unfortunately I had to revert the charlen->size_t patch since it
caused regressions on aix/power (presumably due to endianness issues).
Ah, that explains it. I had forgotten the reversion part.
There's apparently some other process for getting compile farm
accounts nowadays, and we have broken the ABI again for gcc 8, so
maybe I should dust off the patch and try again. Or what do you think?
You can apply at https://cfarm.tetaneutral.net/ . These machines are
indeed quite nice to work on, especially because of the different
architectures (and because there are some very powerful machines
there).
So, any other comments about my patch? OK for trunk?
