-        * XXX fredette - when not compiling PIC, you currently 
-        * can't detect an undefined weak symbol by seeing if 
-        * its address is NULL.  The compiler emits code to find 
-        * _DYNAMIC relative to %dp, the assembler notes the 
-        * needed relocations, but when the linker sees that the 
-        * (weak) symbol isn't defined it drops the ball - the 
-        * relocations are never filled, and the binary ends up 
-        * with code that sees an address of %dp plus zero, 
-        * which != NULL.
-        *
-        * Arguably the linker could/should distinguish between
-        * code that is after a weak undefined symbol's contents 
-        * from code that is after its address.  In the first case, 
-        * it would warn and/or bail.  In the second case, it 
-        * would fix up instructions to give a symbol address
-        * of NULL.
-        *
-        * For now, we take the easy way out and compare &_DYNAMIC 
-        * to %dp, as well as to NULL.
