Description of Problem:
Dejagnu doesn't compile with gcc 3.1 because of its usage of 
non-standards compliant C++ code

Version-Release number of selected component (if applicable):
1.4.1-3

How Reproducible:
100%

Steps to Reproduce:
1. rpm --rebuild dejagnu-1.4.1-3.src.rpm

Actual Results:
c++ -DPACKAGE=\"dejagnu\" -DVERSION=\"1.4.1\"  -I. -I.      -I../.. -g -c 
unit.cc

                 from unit.cc:4:

This file includes at least one deprecated or antiquated header. Please 
consider using one of the 32 headers found in section 17.4.1.2 of the C++ 
standard. Examples include substituting the <X> header for the <X.h> 
header for C++ includes, or <sstream> instead of the deprecated header 
<strstream.h>. To disable this warning use -Wno-deprecated.

Expected Results:
package rebuilds

Additional Information:
STL classes are (enforced) in namespace std these days.
Adding "using namespace std;" will probably be a sufficient fix (and 
won't break older compilers, unless they're old enough to not support 
namespaces at all)
