AC_FUNC_STRERROR_R: Include string.h in test program.
I misremembered how AC_LANG_PROGRAM works. We don’t need to invoke
AC_INCLUDES_DEFAULT here but we *do* need to explicitly include
string.h.
Unfortunately we have no good way of testing for this regression with
the testsuite as it is today.
* lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R): Include string.h in
test program.
