i could have figured that out. but i need the autotools switch anyhow.

its pretty similar. but the src/Makefile is split into 4 and it installs
a shared lib and a plugin. it's just a draft. for example it might fail
in some cases where $builddir!=$srcdir. it also lacks -DUNIX...

it's in the "build" branch. when you do a 'git clone' you mostly get a random
branch. try "git checkout <branchname>" or pass "--branch <branchname>" to
clone.

"gitk --all" is your friend.
