This patch contains some workarounds specially needed for Solaris 11.

Due to

    18617452 SIZEOF_WCHAR_T undefined in pyconfig.h on 11.2

SIZEOF_WCHAR_T isn't ever defined, leading to poor support of wchar_t and

unicode.  Defining that constant prior to including wchar_helper.h helps

work around most of the resulting test failures.

In Solaris 12, libnsl has been turned into a filter library for libc, and

symbols like inet_ntoa are available directly from libc.  But this has not

happened in Solaris 11, so opening libnsl is required in order to find that

particular symbol.
