RE: enlightenment & Eterm

["Harold Hunt" <huntharo at msu dot edu>]

Alan,

I implemented your patches, but compilation fails when UseCygIPC is NO or
undefined, as HasShmDefines is not defined in those cases, so
StandardDefines gets the string 'HasShmDefines' rather than the value of
HasShmDefines.

I added a define for HasShmDefines to /**/ when UseCygIPC is NO.
