I generated a .so with 

        void foo (void);
        void foo (void) { int x(1); x++; }

and, using the same compiler flags that Jam is, was able to build the
.so without the link errors. Very strange.

I started over with a clean copy of boost_1_31_0 and build using:

        bjam -sTOOLS=gcc stage

With the same sort of errors:
