i686-pc-linux-gnu, Red Hat 6.1
>Description:
--pedantic-error causes compilation failures when
--pedantic is silent.  This happens only on RedHat 6.1,
not sure why.   This fails similarly in 3.0.1 and 3.1.
>How-To-Repeat:
echo "#include <cmath>" > foo.cc
g++ -c -O --pedantic foo.cc
g++ -c -O --pedantic-errors foo.cc

For me, the first yeilds no warnings or errors, while
the second yeilds:
