Thanks for the report.
wcwidth is supposed to be declared in wchar.h,
but the above suggests something is not working.
Does your lib/wchar.h file look ok?
Here's the relevant part of mine from a Fedora 12 system:
/* Return the number of screen columns needed for WC. */
#if 1
# if 0
# undef wcwidth
# define wcwidth rpl_wcwidth
extern int wcwidth (wchar_t);
# else
# if !defined wcwidth && !1
/* wcwidth exists but is not declared. */
extern int wcwidth (int /* actually wchar_t */);
# endif
# endif
#elif defined GNULIB_POSIXCHECK
# undef wcwidth
# define wcwidth(w) \
(GL_LINK_WARNING ("wcwidth is unportable - " \
"use gnulib module wcwidth for portability"), \
wcwidth (w))
#endif
