link once (simulating c++ template code in pure c with GCC extensions)

The following definition will be merged in all compiled object files, i.e. the first function implementation will be linked into the produced binary and the following copies rejected.

__attribute__((section(".gnu.linkonce.c"))) int commonFunc(int a, int b) {
    return a-b;

Ubuntu 9.04 on HP Compaq 6510b

Core2Duo T7250, 2GB, intel 965

LiveCD runs fine, all hardware works.
After installation everything works just fine except compiz -- it doesn't run, although 3D games like TuxRacer, Chromium etc. run smooth.
