Re: Sun Studio: STL libraries

[Dan Lacher]

Even with what Tim has pointed out I am seeing the contrary with the 
following:

  o Open MPI src base
  o Sun Studio 12
  o libtool 2.1b (just downloaded the latest)

After autogen has finished the aclocal.m4 ends up with -library=Cstd 
-library=Crun both.  So that is what is used in the creation of the 
libmpi_cxx.so.0
