widec build error on old Linux libc5

[Alain Guibert]

Hello,

On my old Linux box (Intel Debian bo: kernel 2.0.39, gcc 2.7.2.1,
libc 5.4.33, no gettext) during --enable-widec build of ncurses-5.3 with
20030719 cumulative patch, make fails:

I'm not a build process expert (really not), so I don't know what to do
next as test... Same problem on another box with clean same system. More
or less same problem with unpatched 5.3. No problem to build without
widec.
