g++ -pedantic errors on include files

On my 5.1-RELEASE system, if I compile a C++ program thus:

c++ -O -pipe -march=pentium3 -Wall -W -Wno-long-long -pedantic  wchar.cc -o wchar

The compiler prints many warnings like this:

/usr/include/g++/bits/stl_alloc.h:979: warning: ISO C++ forbids the use of `
   extern' on explicit instantiations

Is there  some way to turn this off?  I don't mind getting complaints about my
own code, but it's kind of pointless to get warnings about system include
