I mean that the test used in the library code is doing the right thing. I
haven't investigated whether the compiler is not handling the lookup correctly,
but I don't think there's a libstdc++ bug here.

Nice, thanks! That would at least make testing possible, though I still think

Loop unswitching is correctly only turned on at -O3+. So you want to move it to
-O2. Note loop unswitching can cause performance problems due to increase of
usage of the icache and such.

The patch for gcc/config/i386/t-cygming added a line:
