Yes, but now you need perl to build, apparently.

cd ../src/desc && perl merge_822 ../functions/*/* > def-linux-i686-14787.tmp
mv ../src/desc/def-linux-i686-14787.tmp ../src/desc/pari.desc
cd ../src/desc && perl gen_proto gp pari.desc > gp_init-linux-i686-14787.tmp &&
perl gen_help gp pari.desc >> gp_init-linux-i686-14787.tmp

I completly for got that src/desc/merge_822 was in perl, sorry...
Maybe the 44kb save is not worth the trouble...

Ah maybe this will allow to fix the problem above bby tweaking the
dependencies.

Well, we could have a target that build all the autogenerated files.
After running it, it should be safe to run parallel build since
normally they should no more modify the source tree?

Cheers,
