I find that compiling a function that mentions __builtin_clz just
results in an "undeclared identifier" error report. I have been
searching in the gcc sources for any indication of support for
I find gcc/longlong.h, but that doesn't get installed for user code.
Are you suggesting that we copy the (uglified) contents gcc/longlong.h
into the set of headers released with libstdc++? Most likely users
would like to have those functions ready to hand.
