Yes, but only with Digital's compiler:

alphaev67-dec-osf5.1$ ../configure --enable-changeword CC=gcc |
> fgrep wcwidth
  checking for wcwidth... yes
  checking whether wcwidth is declared... yes
alphaev67-dec-osf5.1$ fgrep WCWIDTH config.h
#define HAVE_DECL_WCWIDTH 1
#define HAVE_WCWIDTH 1
alphaev67-dec-osf5.1$ ../configure --enable-changeword CC=cc |
> fgrep wcwidth
  checking for wcwidth... yes
  checking whether wcwidth is declared... no
alphaev67-dec-osf5.1$ fgrep WCWIDTH config.h
#define HAVE_DECL_WCWIDTH 0
#define HAVE_WCWIDTH 1

ACK,

Here is the culprit:

configure:14791: checking whether wcwidth is declared

Seems like our machine might have a different include search path?
Not sure what to make of that error :-(  It's worth noting that this
machine is used to build several hundred open source projects without
too much difficulty (including large projects like gnome and kde)
using the same compiler:

alphaev67-dec-osf5.1$ cc -V
Compaq C V6.5-303 (dtk) on Compaq Tru64 UNIX V5.1 (Rev. 732)
Compiler Driver V6.5-302 (dtk) cc Driver

HTH,
        Gary.
