wcwidth(0x3000) and wcwidth(0xFF1A) should both be 2; test-wcwidth.c
verifies this.
Here is a proposed patch, to ensure that wcwidth gets overridden by gnulib
on this system.
2016-01-20 Bruno Haible <br...@clisp.org>
wcwidth: Replace also on OpenBSD 5.8.
* m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Check the value of wcwidth(0xFF1A).
* doc/posix-functions/wcwidth.texi: Update.
