 It occurs to me that he might want the implicit extern "C" behavior.
 Unfortunately, unlike all the other effects of system-headerness, that
 is not triggered by -isystem, and there's no way to get it on the
 command line.  It wouldn't be hard to add a switch; I never did
 primarily because I couldn't think of an appropriate name.
 
 Leaving out the -I altogether may be your best bet, Daniel.  I don't
 know where it's coming from - Imake?  If so, that can be edited out of
 the imake templates (in /usr/openwin/lib/X11/config, probably).

 I do suppose I am responsible for the sstream for 2.95.*.
 
 I would like to know what version of sstream you have used.
 
 There should be a line in the file sstream that reads
 * Written by Magnus Fromreide (magfr@lysator.liu.se). */
 
 Unless the line following that one reads
 /* seekoff and ideas for overflow is largely borrowed from libstdc++-v3 */
 
 you would be well adviced to fetch a new version from
 
 http://gcc.gnu.org//cgi-bin/cvsweb.cgi/~checkout~/gcc/libstdc++/Attic/sstream?rev=1.2
