Some more of this, this time needed for Solaris OpenIndiana.


2019-12-04  Bruno Haible  <address@hidden>

        Disable more _GL_CXXALIASWARN on all platforms other than glibc systems.
        * lib/wchar.in.h (wcsnrtombs, wcwidth, wcswidth): Disable
        _GL_CXXALIASWARN invocation on non-glibc systems.
        * lib/wctype.in.h (iswalnum, iswalpha, iswcntrl, iswdigit, iswgraph,
        iswlower, iswprint, iswpunct, iswspace, iswupper, iswxdigit, wctype,
        iswctype, towlower, towupper): Likewise.
