Subject: Re: [musl] [PATCH] fix return value of wcs{,n}cmp for near-limits
 signed wchar_t values

Wait, disregard that suggestion. It doesn't work when the difference
comes out at 1. Works for all other values, but if the difference is 1,
the shift makes it 0, and that means something different for these
functions.

Ciao,
