6796 dnl Try to get _XOPEN_SOURCE defined properly that we can use POSIX functions,
6797 dnl or adapt to the vendor's definitions to get equivalent functionality,
6798 dnl without losing the common non-POSIX features.
6801 dnl $1 is the nominal value for _XOPEN_SOURCE
6802 dnl $2 is the nominal value for _POSIX_C_SOURCE
