According to gnulib's ChangeLog, wcwidth.h was removed in July 2007.
It looks as if we have out-of-date files in the repository.

* lib/wchar_.h: Include the GL_LINK_WARNING macro.
(wcwidth): New declaration.
* m4/wchar.m4 (gl_WCHAR_MODULE_INDICATOR, gl_WCHAR_H_DEFAULTS): New
macros.
(gl_WCHAR_H): Require gl_WCHAR_H_DEFAULTS. Don't set WCHAR_H to empty
here. Prepare for creating <wchar.h> unconditionally.
* modules/wchar (Depends-on): Add link-warning.
(Makefile.am): Substitute also GNULIB_WCWIDTH, HAVE_DECL_WCWIDTH,
REPLACE_WCWIDTH, and GL_LINK_WARNING.
* lib/wcwidth.h: Remove file.
* m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Require gl_WCHAR_H_DEFAULTS. Set
HAVE_DECL_WCWIDTH, REPLACE_WCWIDTH, WCHAR_H.
* modules/wcwidth (Files): Remove lib/wcwidth.h.
(configure.ac): Invoke gl_WCHAR_MODULE_INDICATOR.
(Include): Replace wcwidth.h with <wchar.h>.
* lib/wcwidth.c: Include <wchar.h> instead of wcwidth.h.
* lib/mbchar.h: Don't include wcwidth.h.
* lib/mbswidth.c: Likewise.

* lib/wcwidth.c: New file, extracted from lib/wcwidth.h.
* lib/wcwidth.h: Don't include wctype.h. Replace inline function
definition with an external declaration.

defined as a function. Remove AC_C_INLINE requirement.
* modules/wcwidth (Files): Add lib/wcwidth.c.
