XINST fuse for PIC18F2525 - problems

I have just spent 2 days trying to get a simple test program that runs on a 16F876A to run on a 18F2525. I tracked it down to the XINST fuse being set
ie
#FUSES XINST //Extended set extension and Indexed Addressing mode enabled

The code would not run. In a simple fgetc and fputc test the value was always wrong. Removing this fuse corrected the problem. And yet, the new project wizard set this for me automatically. What am I missing here. Is this a IDE bug? I assume the compiler cannot make valid code with this set.

It's a bug in the Wizard. I emailed CCS about this a few months ago.
I explained to them how it's going to cause problems with whoever has
that version of the IDE. They didn't reply to me. That's all I can do.

Here is one of the earlier threads on this:

Thanks.
I love the compilers but have been disappointed with the support. That little bug just cost my employer 2 days pay while I battled with it. If they could only list a known bugs list instead of relying on their users to provide the customer support.

Oh well......
