This is undoubtedly my fault, for not checking the other binaries.
I've been under the weather recently, and i've only been checking
the gift-extract-features binary.
I'll try to get a fix in sometime this evening..
Yes, normally C screams and yells at you, but the gift was written
without function prototypes, so the compiler cant tell, until link time.
I'll also whip up a quick patch adding function prototypes, and post
it to the mailing list, for review.
Back, after being food poisoned,
