Well, I'm not sure.  It definitely doesn't work in the preprocessor;
that's where we started.  It appears to work otherwise - as in, Lua
builds - though I haven't inspected the (other) uses of those macros to
tell how much, if anything, that means.

I left off the LL/ULL suffixes because of the preprocessor; I did not
expect it to understand them.  But it doesn't seem to handle them
without the suffixes either, so I'm not sure.  I should perhaps try it
with the suffixes.

> Also the typedef required __extension__ as such .. in 1999?

Which typedef?  As in, "typedef long long int foo;" required
__extension__?  The compiler I've got doesn't need that, that's about
all I'm certain of.  I've tweaked it a little, but I don't _think_ I
did anything that bears on handling of long longs.

Yes, using -ansi -pedantic with that compiler produces warnings about
how "ANSI C does not support long long" or some such.  (I can dig up
the exact message if you want.)

I was actually quite delighted - astonished, but delighted - by how
little bludgeoning Lua required to build.  I am not used to other
people's software (possibly excepting the trivial 50-line sort)
building on my machines with only minimal tweaks.

I was also delighted - again, astonished but delighted - by how little
of the GNU koolaid Lua has drunk.  I was expecting to be faced with
./configure (which, because of the huge pain they are, usually lead to
me tossing the whole thing out as a result).  It doesn't even depend on
GNU make!

And, when I was reading the documentation, I was very impressed at how
much mileage Lua gets out of the one data structure it supports.  It's
an excellent example of one well-done choice producing a cornucopia of
consequences.  The only comparable example I can think of offhand is
what Lisp does with conses.
