argp-fmtstream.c:371: error: ogiltiga operander till binär -

The macro for fwrite_unlocked in libio/bits/stdio.h fails to put its argument n
within parantesis at the penultimate line:

...
                        /* Evaluate all parameters once.  */                  \
                     ? ((void) (ptr), (void) (stream), (void) (size),         \
                        (size_t) n)                                           \
                     : fwrite_unlocked (ptr, size, n, stream))))

so (size_t) n gets expanded to 
  (size_t) fs->p - fs->buf
which turns into a binary - with incompatible operands.
