Help with link error

I am trying to embed mozilla in an application.  I am starting by 
writing a simple example. Everything compiles fine, however I get the 
following link error. The source and  makefile are below. Any help would 
be appreciated.

Environment:

gcc-3.2
glibc-2.2.5
Gentoo Linux 1.4(RC1)

Error:
> Main.o(.gnu.linkonce.d._ZTI14nsAFlatCString+0x8): undefined reference to `typeinfo for nsASingleFragmentCString'
> collect2: ld returned 1 exit status
> make: *** [htmlcontrol] Error 1
