"What steps will reproduce the problem?"

Run cppcheck on a source file that contains errors, warnings, and style issues.

"What is the expected output? What do you see instead?"

The application should report errors, warnings, and style issues in the
Problems Tab of Eclipse.  However, only errors are being reported. 

For Reference, I ran the CppCheck 1.4 GUI where it displayed all three
types of issues.

"What version of the product are you using? On what operating system?"

cppcheck =  version 0.94
Eclipse: Galileo CDT, version 3.5
OS: Windows XP
