Can't reproduce on AIX 5.1.
PHP itself is linked with libm, so it should not matter whether
extension itself is linked or not.

Description:
------------
Building PHP 5.1.6 on AIX 5.2. GD compiled in shared mode. gd.so is
linked without the math library (-lm). Then, when loading the GD
extension, we get an error for all the math functions it is using
(sqrt(), ...).
Workaround: after having built everything and before install :
rm ext/gd/gd.so
gmake LDFLAGS="$LDFLAGS -lm"
and, now, it can be loaded.
Reproduce code:
---------------
./configure --with-gd=shared
and then loading gd.
Expected result:
----------------
load OK
Actual result:
--------------
I don't have the exact messages but they are all about unsesolved
symbols from the math library (there is at least sqrt()).
