What does "grep WCWIDTH config.h" show? Does it show
#define HAVE_DECL_WCWIDTH 0 ?

It should say
#define HAVE_DECL_WCWIDTH 1
because of the
    extern int      wcwidth         __((const wchar_t));
declaration in /usr/include/wchar.h. Can you look in the config.log why
it set HAVE_DECL_WCWIDTH to 0?

On a different OSF/1 5.1 machine, also with cc, I get
$ grep WCWIDTH config.h
#define HAVE_DECL_WCWIDTH 1
#define HAVE_WCWIDTH 1
and all goes fine.
