Any chance this could please be recast as

        int b2 = wctob((unsigned char) b);
        if (b2 == EOF || b2 == b)
        ...

The reason is that gawk still supports C90-only compilers (I have users
wit such compilers) and the declaration after executable code won't fly
in that case.

This also makes only one call to wctob() instead of two. :-)

Thanks,

Arnold
