I think you do have. up-to-date?

yes, I posted the relevant snippet of this func_win32_libid function, so 
that you can check what's going on with your objdump and nm on your 
libpthread.a
But you have a different/unsupported build so you should really step 
through your relevant func_win32_libid() function.

because it overrides the check. it passes no args to the func.
