The --help output of gettext's configure contains these lines:
$ ./configure --help | grep libuni
--with-included-libunistring use the libunistring parts included here
--with-libunistring-prefix[=DIR] search for PACKLIBS in DIR/include and
DIR/lib
--without-libunistring-prefix don't search for PACKLIBS in includedir and
libdir
The reference to PACKLIBS is a bug; the correct output ought to be:
--with-included-libunistring use the libunistring parts included here
--with-libunistring-prefix[=DIR] search for libunistring in DIR/include and
DIR/lib
--without-libunistring-prefix don't search for libunistring in includedir
and libdir
This patch fixes it. Apparently the bug dates back to 2008.
