No, just enable it unconditionally. There's a number of packages that are currently disabled on uClibc because it lacked fenv support. > uClibc-ng also gained support for uchar functions a while back. > tpm2-tools needs it. It adds approx. 5kb to the C library. > What should we do here? Enable uchar automatically, when wchar is enabled? Yes, enable uchar when wchar is enabled seems like a good idea.
