5728,sendmsg.c does not compile on Solaris,toddmowen,,"We are trying to upgrade from version 11 to 12, on a Solaris 5.10 box with Python 2.7.

The Twisted-12.0.0 release builds without error. However, the later Twisted-12.1.0 release produces the following error during `python setup.py build`:

It appears that on this platform it is necessary to define the `_XOPEN_SOURCE` and `_XOPEN_SOURCE_EXTENDED` macros in order to gain access to the `msg_control`, `msg_controllen`, and `msg_flags` members that the errors mention (according to http://stackoverflow.com/questions/1034587).",defect,new,normal,,core,,Solaris review,xaka2004@…,,,
