Details:

lib/error.c contains old configuration checks for strerror_r, and it assumes
that strerror_r should return char*, while now the standard is to return
int.

This conjunction can cause a conflict with the strerror_r provided by the
host, and error messages printed through the error() function can get
garbled, because the return value of strerror_r is passed to printf to fill a
%s.

The quick solution is to remove references to lib/error.c and lib/error.h in
the package, and use the functions already available in the system.

A better solution for the long term would be to fix the configure script and
update from gnulib.
