Not sure about this. The other change (to s-oscons-tmplt.c) causes
SOSC.MSG_WAITALL to always be defined to 8 in the Windows case, so the
new test against -1 (which would have been relevant without the other
change) now becomes redundant.

The comment is completely meaningless and should be rewritten. In
particular a note should be added to explain why this will work even
though MSG_WAITALL is not defined in the Winsock header files.
