Not what's in the tree.  I was using this in my local branch, because I couldn't
build cl_nodenamemap without out it.  I removed this change when I submitted the
patches, under the false assumption that the build still worked.  (I didn't
force a clean build after changing the sources file; I assumed that it was smart
enough to figure out that changes to the make files should cause a rebuild.

I'm not convinced this is true.  The issues that you referenced only mentioned
that there can be problems if you pass CRT objects through the DLL interface.

If complib isn't using the CRT now, then we should be safe.

No - cl_nodenamemap is a small wrapper over cl_quickmap, where the keys are
strings of data than may be read from a file.  It is desirable to return complib
back to a single set of interfaces that are common across different platforms.
Otherwise, it's pointless, and native interfaces should just be used instead.

As alternatives, cl_nodenamemap could be compiled directly into each ib-diag
that requires it, plus opensm (eventually), or it could become its own library.
