In fact, it seems like the build problem comes from gnulib, which is
bundled in pax-utils. Usage of wctomb() was recently added in gnulib as
of commit 5cdec0ff5ecf34474d90d8b57f50a148449cda0c. And it seems like
there is code to not use wctomb() when wchar support is not available,
but that logic doesn't seem to work.

I don't really care about pax-utils being not available with wchar
disabled, but since gnulib is also used in lots of other projects, I'm
fearing that we might see this issue elsewhere.

Could you check if the pax-utils copy of gnulib lib/vasnprintf.c
includes commit 5cdec0ff5ecf34474d90d8b57f50a148449cda0c and report a
bug to upstream gnulib ?

In the mean time, I have applied your patch, with an extended commit
log.

Thanks!

Thomas
