-pedantic shouldn't change something from OK into an error, but it was
doing so for redeclaration of a declaration from a system header with a
mismatched exception specification. And whether we are strict about things
in system headers should be controlled by -Wsystem-headers.
Tested x86_64-pc-linux-gnu, applying to trunk.
The new g++.dg/warn/Wsystem-headers1.C test FAILs on Solaris 10 and 11:
FAIL: g++.dg/warn/Wsystem-headers1.C -std=c++98 (test for excess errors)
