+musl doesn't support the locale things that the locale requirements test, like
+localized money and decimal formatting.
+
+The syscat.errcat tests are broken and rely on the libc to return a specific
+string in the form of "Unknown error <n>" for unknown errnos when calling
+strerror(), which is not defined anywhere and libcs are free to return any
+string they want, up to and including "libcxx tests are silly".
+
+Similarly to glibc, musl uses "NaN" to format NaN long doubles, not "nan".
+Finally, musl uses "0" to indicate a NULL pointer as %p argument to *printf().
