Probably so. Unfortunately, the code I am compiling uses ELF or GCC
constructor language extensions to request that an initialization
function be executed.

Ok. I will take a look. Unfortunately, it seems that I will need to
modify the code since it also expects/requires __STATIC__ to be
defined for static library builds.
With the latest CVS libtool (which is what I am using) I assume that I
can update the 'pic_flag' variable directly since libtool is not
written out until the end of the configure run.
