- Portablility fix: We now control the name to be used in the assembler
    code for a C function or variable.
    GCC for Win32 normally prepends an underscore to the name of a
    C function or variable, and the inline assembler code was using the
    name without the underscore so we had undefined symbols in some
    modules.
- Reenabled all the accelerated modules on Win32.
