[phc-general] auto{conf,make} portability patch

[Edsko de Vries]

Hi Conor,

First of, thanks for your long bug report. However, I have actually
build phc on Mac OS X, without difficulties. You are right in saying
that -rdynamic is not recognised by gcc, but I found that it simply
ignores it, rather than trowing up an error and aborting compilation -
which is why I haven't bothered so far to remove it (as far as I
remember, on the Suns, -rdynamic is unnecessary too, but also ignored).
Did gcc on your Mac actually stop compilation, or just complain error
and continue? Of course, not checking if -rdynamic is required was just
laziness on my part, so now that you've done the work, I'll gladly apply
the patch :-)

The test framework has actually changed quite a bit since then, and Paul
has already integrated configure with the tests (the tests now include
an autovars.php, generated from autovars.php.in by configure) - so don't
bother for the moment. If the new release (or I could send you a
pre-release if you want) still doesn't solve these problems, let us know.

I've just run it and it seems to work, both on my machine (Debian/x86)
and on my Sun.  

As for further testing, we are currently working on the code generator,
which is coming along nicely, but will it will take some time to get it
finished :) 

> Happy New Year,

You too, and thanks again,
