    Hello,

    I am building a -fPIC shared object that will define and access a Linux
    kernel system call, but _syscall2 fails with -fPIC .so compilation.
    What can I do?
     
            F.E. the statement:
     
    _syscall2 (int, tux, unsigned int, action, user_req_t *, req)
     
    Gives the following gcc error when compiled with -fPIC:
     
    tst.c: In function `tux':
    tst.c:62: Invalid `asm' statement:
    tst.c:62: fixed or forbidden register 3 (bx) was spilled for class
    BREG.

    If the -fPIC isn't there it compiles fine. Unfortunately I need to find
    another way as I have to use -fPIC.

    Thanks in advance for any suggestions.
