-Building GiNaC requires many standard header files. If you get a
-configure error complaining about such missing files your compiler and
-library are probably not up to date enough and it's no worth
-continuing. If the only file missing is <sstream>, however, there is
-a solution. GCC-2.95.2 and earlier don't ship with this file. A
-working implementation has been available since GCC-2.95.3. GCC-3.0
-and later have an even better, fully standard-conforming
-implementation, by default. If you are stuck with GCC-2.95.2 or
-earlier and you cannot upgrade your compiler we recommend obtaining
-the libstdc++-v2 <sstream> header written by Magnus Fromreide. It was
-posted to the gcc-patches mailing list on November 21 2000:
