[Bug-readline] Unused support/wcwidth.c

[Jan Kratochvil]

Hi,

not a real bug but this file is still being shipped:
-rw-r--r-- chet/wheel    13989 2008-08-11 16:31 readline-6.2/support/wcwidth.c

while I do not see how it could be used.  Could it be removed?

rlmbutil.h does not define HANDLE_MULTIBYTE if !defined (HAVE_WCWIDTH).

There was a patch to use wcwidth.c in the past but I do not see it applied in
readline-6.2.  The time the patch was posted HAVE_WCWIDTH was not
a prerequisite for HANDLE_MULTIBYTE as currently is.
        [Patch] correctly configure wcwidth in readline

        http://sourceware.org/ml/gdb-patches/2003-03/msg00043.html

Tested readline-6.2 on Fedora 14 x86_64 no reference to wcwidth happens when
configure does not find wcwidth.


Thanks,
Jan
