Only some general comments on the patch about things I noticed when I
diffed my diff against yours:

- Interesting, how many mistakes I managed to put into the patch...
and it even compiled on my system (with lua).
- Please use real TABS in acinclude and configure patches. Your current
patch just breaks indentation in these files when used with the only
standard tabwidth (8). Using Spaces instead of TABs is not even allowed
at the beginning of lines of makefiles (it will break on older make
implementations). That's why I changed the whitespace in the Makefile.am
(which you kept in your version of the patch - it's just a general
remark).
- I'm not really sure that you really need to check as thoroughly as you
currently do - if someone has a partial/invalid installation of lua,
they just might fail and fix their installation ;) - but that's a matter
of taste. What I don't like ist the check for the exact version. That's
not the spirit of autofoo: We check for the availablility of
features/functions, not versions. Are you sure your code won't work with
lua 5.0.1 or 5.0 or 4.x? What happens when 5.0.3 is released? How about
skipping that check for now and wait for break reports?

It dowsn't even build on my system: It looks like the addition of lualib
added some depenency on -lm or something like this...

/usr/lib/liblualib.so: undefined reference to `log'
/usr/lib/liblualib.so: undefined reference to `sqrt'

Also, I don't have any sample testcode, or how was I to check whether it
actually works?

Good night

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
