+/* Ensure all the Exxx constants required by convert_wsa_error_to_errno() in
+ * win32/win32sck.c are defined. Many are defined in <errno.h> already (more so
+ * in VC++ 2010 and above and some MinGW/gcc-4.8 and above, which have an extra
+ * "POSIX supplement") so, for the sake of compatibility with third-party code
+ * linked into XS modules, we must be careful not to redefine them; for the
+ * remainder we define our own values, namely the corresponding WSAExxx values.
+ *
+ * These definitions are also used as a supplement to the use of <errno.h> in
+ * the Errno and POSIX modules, both of which may be used to test the value of
+ * $!, which may have these values assigned to it (via code in win32/win32sck.c
+ * and the $! case in Perl_magic_set()). It also provides numerous otherwise
+ * missing values in the (hard-coded) list of Exxx constants exported by POSIX.
+ * Finally, three of the non-standard errno.h values (actually all now in the
+ * POSIX supplement in VC10+ and some MinGW/gcc-4.8+) are used in the perl core.
+ *
+ * This list is in the same order as that in convert_wsa_error_to_errno(). A
+ * handful of WSAExxx constants used by that function have no corresponding Exxx
+ * constant in any errno.h so there is no point in making up values for them;
+ * they are just returned unchanged by that function so we do not need to worry
+ * about them here.
