    You can do:
    if [ "$CC" = gcc ]; then
    echo 'inline void f(unsigned int n){int i,j=-1;for(i=0;i<10&&j<0;i++)if((1UL<<i)==n)j=i;if(j<0)exit(0);}main(){f(64);exit(1);}' > test.c
    gcc -O2 -o test test.c
    if ./test; then echo "*** Please don't use this compiler to compile kernel"; fi
    rm -f test.c test
    fi

    (the $CC = gcc test is there e.g. so that the test is not done when
    cross-compiling or when there is a separate kernel compiler and userland
    compiler (e.g. on sparc64). This test will barf on gcc-2.96 up to -67 and
    on 2.97 until end of November or so).
    Similarly a testcase for the reload bug which caused in 2.95.2
    miscompilation of some long long stuff in the kernel could be added as well
    if you want to go that way.
