[ros-kernel] wcstomb(s).c warnings

[Royce M. I. <ro...@ev...>]

wcstombs.c(91):

   if (wc < 0 || wc > 0x7fffffff)

shouldn't this be:

   if ( wc & 0x80000000 )


same thing in wcstomb.c(87)

   if (wc < 0 || wc > 0x7fffffff)


Now that I think about it, I think this won't
fix the warning, because the warning is
that expression is always false because of
limited range of type.

Perhaps the check should really bw:

   if ( wc & 0x8000 )

since wchar_t is supposed to be 16-bit?
