Xcode Tiger to Leopard duplicate symbols mystery

Hi all,

I just upgraded to Leopard and am trying to build a Tiger project in Leopard. During the Leopard Betas I've tried building my project and have successfully done so several times. Two major changes since the last trial are 1) the addition of a new library 2) i386 only to Universal build. The error is:

ld: duplicate symbol _g_bit_nth_lsf in /Users/.../Objects-normal/i386/ CamDirectConnection.o and /Users/.../Objects-normal/i386/AVController.o

This comes from the glib library which I have inside a framework bundle. The framework is libmimic, which I've built myself into a Universal binary. Each of the .o files referenced above does call some of the libmimic functions, which in turn calls the glib functions. Using 'nm' on each file, I do see _g_bit_nth_lsf in both of them

.
.
.
00000000 T _g_bit_nth_lsf
00000049 T _g_bit_nth_msf
00000098 T _g_bit_storage
0000012d T _g_trash_stack_height
00000114 T _g_trash_stack_peek
000000e2 T _g_trash_stack_pop
000000bc T _g_trash_stack_push
.
.
.

If I do the same to the .o files from the Tiger build, I do not see these lines anywhere, not even in one of the two files. Does anybody have any idea of what going on here?

Thanks in advance.
