The software does not understand Fedora gcc/g++ well.  Just to get started,
I had to add these to the command line:
    -I/usr/lib/gcc/x86_64-redhat-linux/4.4.1/../../../../include/c++/4.4.1 \
    -I/usr/lib/gcc/x86_64-redhat-linux/4.4.1/../../../../include/c++/4.4.1/x86_64-redhat-linux

Then I got several dozen false positives (complaints that were incorrect)
from my first file.  How new is this software?
