dnl ---------------
dnl Try to get _XOPEN_SOURCE defined properly that we can use POSIX functions,
dnl or adapt to the vendor's definitions to get equivalent functionality,
dnl Parameters:
dnl $1 is the nominal value for _XOPEN_SOURCE
dnl $2 is the nominal value for _POSIX_C_SOURCE
+dnl
+dnl The default case prefers _XOPEN_SOURCE over _POSIX_C_SOURCE if the
+dnl implementation predefines it, because X/Open and most implementations agree
+dnl that the latter is a legacy or "aligned" value.
+dnl
+dnl Because _XOPEN_SOURCE is preferred, if defining _POSIX_C_SOURCE turns
+dnl that off, then refrain from setting _POSIX_C_SOURCE explicitly.
