Code Won't Compile in MPLab with WPILib

[Inverted]

Last night I added WPILib to my project so I could use the Wait() function. When I went to compile the code, I got this error:

Executing: "C:\mcc18\bin\mcc18.exe" -p=18F8722 "user_routines_fast.c" -fo="user_routines_fast.o" -Ou- -Ot- -Ob- -Op- -Or- -Od- -Opa- -nw=2066 -D_FRC_BOARD

I believe these values are conflicting with ones in the serial_ports file. Then again, I could be wrong.

Any ideas how to resolve this?

Also, I was a bit unsure of the library files I had to use. Do I only use the two library files included in the WPILib distribution, or do I use the WPILib library and then either the FRC_library or the FRC_alltimers included with the default code?
