Configuration fuses not right

In my ".h" file I set a bunch of configuration fuses. However, my ".lst" file shows me that five of them (out of about 28) set opposite of what I chose. For example, PROTECT comes out NOPROTECT. The other fuses are BROWNOUT, PUT, WDT, AND STVREN. Any ideas? Thanks!

Info: PIC18F4550, CCS version 4.100.

Are you trying to use the ICD to do hardware debugging ?
If so, certain fuses will be automatically disabled by CCS.

From the Microchip ICD2 help file:

Currently, I am not using the debugger. However, I did have the DEBUG fuse set. I removed that fuse, re-compiled, and the same five items come up with a big "NO". More ideas?

If you need more help, then post a very short, but compilable test
program that demonstrates the problem. Don't put a lot of useless
wizard code into it. Make it be very minimal. But it must compile
without errors.

Hey thanks, PCM programmer! While stripping down my code to demonstrate the problem, I found that I had to delete both "#device ICD=TRUE" and "#fuse DEBUG". I had tried one, then the other. Turns out I needed to do both to get my configuration bits right. Thanks again!
