ehhmm..

[root@fogarty /tmp]# rpm -q gcc
gcc-2.96-70
[root@fogarty /tmp]# cat test.c
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);}
[root@fogarty /tmp]# gcc -o test test.c
[root@fogarty /tmp]# ./test

didn't barf here with 2.96-70.
