I don't have a i386 with osx, but I gather from this checkin that .hidden<br>
doesn't work. Could someone try ".private_extern" instead?<br>

".private_extern" seems to work for '-format archive'.<br>
But, with '-format library', I get:<br>

<br>A text relocation is where the linker records what locations of the code need to be changed after loading a library. I was hopeful I wouldn't need PIC for i386. :-(<br><br></div></div></div>
