Avoid implementation-defined strerror behaviour
POSIX states that the string returned by strerror() may be overwritten
by a subsequent call (i.e., because it returns a pointer to a static
buffer). Make a copy of one of the two strerror() strings to avoid
this.
Background: FreeBSD historically returned such a pointer only in the
case of an invalid errno. With the addition of NLS strerror was changed
to do so for all calls.
Prior to this change I had confusing results from the test suite like
"... is 22 (Invalid argument) but should be 0 (Invalid argument)".
