Compiled programs don't run on Solaris x86

Hi,

I have built Prolog 1.3.0 on Solaris x86.  (Specifically, OpenSolaris 
build 49, using GCC 3.4.3 modified by Sun.  This is a 64-bit machine, 
but of course a 32-bit build of Prolog.)

The interpreter comes up and seems to work fine; at least, some simple 
test queries succeed.  The compiler runs and produces an executable, but 
the executable crashes with a SEGV on startup.  This is true even for a 
trivial program like

  :- initialization(main).
  main :- print(hello), nl.

I tried running the executable under GDB, and what I find is that 
`Rd_Callable_Check' has been passed a `start_word' of 0.  Beyond that, 
it's hard to see what's going on since there are no frame pointers.
