But Linux/x86 and Linux/x86-64 have no problems. The error message looks like

pass41-frag.o: In function `global constructors keyed to
0_main':/net/gnu-13/export/gnu/src/gcc-4.1-blended/gcc/libmudflap/testsuite/libmudflap.c++/pass41-frag.cxx:13:

...

Those undefined symbols are from things like:

 struct __ios_flags
  {
    typedef short __int_type;

    static const __int_type _S_boolalpha = 0x0001;
    static const __int_type _S_dec = 0x0002;
    static const __int_type _S_fixed = 0x0004;
...

Mudflap generates

        .mii
        addl r35 = @ltoffx(_ZNSt11__ios_flags12_S_boolalphaE#), r1
        addl r38 = @ltoffx(.LC72), r1
        ;;
        nop 0
        .mmb
        ld8.mov r35 = [r35], _ZNSt11__ios_flags12_S_boolalphaE#
        ld8.mov r38 = [r38], .LC72
        br.call.sptk.many b0 = __mf_register#

I don't see why it should even bother. This problem doesn't exist in 4.2. Does
anyone know which patch fixes it?
