Yes. I finally found a way to get it to compile. Compiling without TT mode and WITHOUT static build it still fails with the same problem (__bb_init_func problem I already reported). But compiling without TT but WITH static build the __bb_init_func problem goes away but instead I get a __gcov_init missing symbol in my modules. Note I have gcc-3.3.4-11 (SuSE 9.2) and it defines __gcov_init. So I added this as an export symbol and lo and behold the kernel and modules compiled and I am now up an running with UML and NTFS as a module.
