Exit code -1 cause found (SGN)

[boriel]

If I have a unsigned variable (e.g. UBYTE) and want a SGN of it, the compiler produces a warning that it can then be only 0 or 1, but the compiler exits with exit code -1. Should be the warning not mean, it can be compiled anyway?
I'm using version 1.4.0s1968.

Hmm. You're right. I'll fix that.
