fix extrefs text with SDK 2003

The attached patch (also inlined below) fixes the SDK2003 test failure
for me, and also passes with all the other VC++ compilers. (It isn't
easy trying to pinpoint the SDK2003 compiler individually, so it is
simpler to just do this for all VC++ compilers on Windows.)
