Oh yeah, misreading '1' and 'l' (and I) is classic. There's a reason a lot of countries have restrictions on characters like those appearing on car license plates. But if it helps you remember it, the 'l' in -Wl stands for linker - it's the mechanism for providing parameters that should be passed through to the linker (which gcc invokes), not read by gcc itself. So for example, passing "-Wl,--verbose" to gcc means that gcc will pass "--verbose" when it runs ld. Simon.
