How to get around MacPorts assuming that Exit code: 1 is a failure?

[Eric Gallager]

I am working on a Portfile from which I want to call the `unifdef` command.
The manpage for `unifdef` says: "Exit status is 0 if output is exact copy
of input, 1 if not, 2 if trouble." The whole reason I am running `unifdef`
is to change the output, so I *want* it to return 1. However, when I put
this in my Portfile, it interprets this as a failure. Is there any way that
I can get around this?
