1. In cygwin-devel v3.0.2-1, <cygwin/socket.h> does not #define MSG_EOR.
In bash, with CWD=/usr/include, the command "find . -name '*.h' -exec grep -Hn MSG_EOR {} \;" does not find any matches.
2. The Open Group man page for <sys/socket.h> contains the following excerpt regarding #define MSG_EOR:
The <sys/socket.h> header shall define the following symbolic constants with distinct values for use as the valid values for the msg_flags field in the msghdr structure, or the flags parameter in recv(), recvfrom(), recvmsg(), send(), sendmsg(), or sendto() calls:
...
MSG_EOR
Terminates a record (if supported by the protocol).
...
3. Reproducing the bug
3.1 This bug occurs at compile time.
3.2 Code snippet
#include <sys/socket.h>
#define BUF_SEND_NUM_BYTES 1024
int socketFdIpv4 = socket(AF_INET, SOCK_RAW, IPPROTO_IP);
(invocations of bind(), accept(), listen(), connect() - not needed to reproduce the compile time problem)
char bufSend[BUF_SEND_NUM_BYTES];
(initialization of bufSend contents omitted - not needed to reproduce the compile time problem)
ssize_t sendReturn = send(socketFdIpv4, bufSend, BUF_SEND_NUM_BYTES, MSG_EOR | MSG_OOB);
3.3 Compiler command
gcc -c -Werror -DPOSIX_FLAVOR=POSIX_OPEN_GROUP -DSCA_4_1_OE_AEP_FULL -o jtelSca4_1TestCaseOeAepProviderUofProfileFull.o jtelSca4_1TestCaseOeAepProviderUof.c
3.4 Compiler output
error: ‘MSG_EOR’ undeclared (first use in this function); did you mean ‘MSG_OOB’?
ssize_t sendReturn = send(socketFdIpv4, bufSend, BUF_SEND_NUM_BYTES, MSG_EOR | MSG_OOB);
^~~~~~~
MSG_OOB

MSG_EOR is not supported by underlying WinSock. There's a similar
MSG_PARTIAL, but it's defined differently. It's also unsupported by
all of the predefined protocols, including UDP.
Since MSG_EOR isn't implemented in the underlying transport layer,
there's no way to implement it in userspace. That's why it's not
defined in Cygwin's headers. If you have an idea how to implement
this in plain userspace, feel free to provide patches.

I don't have a direct interest in this issue, but I do have a wondering.
If Cygwin fails to define an error code -- even if the error cannot
actually happen under Cygwin -- isn't that a problem when trying to
compile imported software? I wouldn't mind if the code were defined,
and a note included in comments that the error will not actually
occur under Cygwin ...
Is this a reasonable argument in support of including a define of the
error code?

That, like the question whether Cygwin is in any way obliged to define
it, ends up in an issue of Interpretation of Standardese. The latter is
a language that looks deceptively much like ordinary English, but just
like Legalese, is not the same thing.
In the case at hand the point that needs interpretation is what that
parenthesis "(if supported by the protocol)" really means. What is "the
protocol" it refers to? What if several protocols are supported, which
differ in support for this?
The core issue, though, is: what is controlled by this "if", i.e. what
is the "then" effect? And what's the "else"?
Cygwin's interpretation (whether by design or by accident) is: if this
never is true, the "shall define" a few lines above does not apply any
more. If that's a correct interpretation, then source code would be
wrong to just assume presence of this macro unconditionally. In that
case the actual problem that software noticing would be written
incorrectly (they should #ifdef MSG_EOR before using it).
An alternative interpretation could be that this entire parenthesis is
ultimately just a superfluous that adds no meaning to the standard; the
macro would have to be defined always; software would be entitled to
blindly assume its existence, and Cygwin would be wrong about this.
Either way, as Standardese goes, this is sufficiently unclear that it
IMHO calls for a defect report to the governing body of this standard.

Well, MSG_EOR is not an error, but we can certainly do better than not
defining it at all. My suggestion for the least-cost implementation:
- add a define for MSG_EOR to a non-zero value that is bitwise distinct
from other required MSG_ values
- return EOPNOTSUPP on attempts to use the flag in
send()/sendmsg()/sendto() (POSIX permits that failure for protocols that
don't support it - and none of Cygwin's protocols support it)
- optionally, document that MSG_EOR will never be set in the results
returned by recvmsg() (POSIX says it will only be set on protocols that
support it - and none of Cygwin's protocols support it)
This will at least let software compile that attempts to use it, and
hopefully that software is robust to the fact that send() may reject the
flag and that recvmsg() cannot reliably report use of that flag.

You're welcome to do so:
http://austingroupbugs.net/main_page.php
although I personally thought POSIX was clear enough that MSG_EOR is
required to be defined, even if only so that it can trigger send()
errors showing that it is unsupported.

Would it be allowed and valid to #define MSG_EOR 0 to simplify lack of support?

Interesting. I really thought it's better that a programm does not
compile, rather than it compiles and misbehaves from the POV of the
developer.
I added the MSG_EOR definition and send(2) and friends return EOPNOTSUPP
now. I uploaded a snapshot to https://cygwin.com/snapshots/ with this
change.
