Re: _lt_libltdl_LTX_preloaded_symbols in consistence.

[Steven Wu]

It was _lt__PROGRAM__LTX_preloaded_symbols, however, in libltdl.a, it  
was _lt_libltdl_LTX_preloaded_symbols. That is why I changed the name  
in ltdl.h.

here:
$ nm libltdlS.o
         U _dlopen_LTX_get_vtable
000002c0 S _lt_libltdl_LTX_preloaded_symbols

and nm libltdl.a
...
nm libltdlS.o
         U _dlopen_LTX_get_vtable
000002c0 S _lt_libltdl_LTX_preloaded_symbols
...

That symbol name was inconsistent with ltdl.h. When I tried to link  
with with -lltdl, and I got the following error. I hence got around  
the problem by changing the macro definition in ltdl.h to match the  
symbol in the ltdl libraries. Hopefully we can find the real solution  
to this problem.
