I am attempting to build wget 1.24.5 from the source tarball, and discovered that `make test` fails to build. A very long investigation revealed that a needed function, uc_width, is not getting compiled into gnulib: it is defined in `lib/uniwidth/width.c`, which theoretically gets compiled into `libgnu-wcwidth.o`, but that never happens because my libunistring's version (1.2.0) triggers the configure script to comment that build instruction out of the Makefile (see the areas around line 62720 in `./configure` and around line 390 in `./lib/Makefile`). I am assuming this to be done by some obscure M4 macro (perhaps one that came with Gnulib?), because libunistring is not referenced at all in `configure.ac`.
I'm going to work around it by either editing the Makefile or installing a newer version of libunistring, but this seemed like something you ought to be told about. Gordon Steemson
