I have a Codewarrior project that was compiling fine in CW10.6 with MQX4.1.1 installed. I installed MQX4.2 and when I tried to open the same project and compile it I'm getting the following errors:

(and there are more like this)
I had already gone through the project settings and updated paths to the MQX4.2 folder, and when I got this message after trying to compile, I also tried changing the "Target Processor" options in the C/C++ Build Settings menu to Float ABI = "FPU with hard vfp passing", and FPU Type = "FPv4-SP-D16" From some online searcing, this error seems to be related to the hardware floating point unit. But I continued getting those errors.
I also tried creating a new project based on an example project and copying my source into, adding relevant libraries, etc., but I ran into other problems which I'm working through. But I would prefer to know how to fix the issue with the original project. Any thoughts?
Thanks
