[reSIProcate] resiprocate build warnings

["Alfred E. Heggestad" <aeh@xxxxxx>]

hi

I am getting some warnings when building resiprocate from svn r6799:
(g++ (GCC) 4.1.2 20060901 (prerelease) (Debian 4.1.1-13))


MsgHeaderScanner.cxx: In member function ‘resip::MsgHeaderScanner::ScanChunkResult

testSipMessage.cxx: In function ‘int main(int, char**)’:
testSipMessage.cxx:232: warning: value computed is not used


not sure about what this line is supposed to do:

testSipMessage.cxx:232

         message1->header(h_StatusLine).statusCode() == 407;




this patch should fix some of them:
