When you ran configure, was g++ correctly configured to find the
include files in /usr/lib/g++-include?  If so, Octave's configure
script should have found the definition for NPOS in <string>, or it
should have found that the C++ string class has npos as a data
member.  I'm not sure whether the above declaration is correct, but
you can probably work around it by removing the definition of NPOS
from Octave's config.h file and running make again.
