ANCI C? What is that - a NASA invention?

In a recent article in Vision Systems Design, March 2005, there is an description of NASA's Shuttle heat-shield tiles measurement system, consisting of - among others - an imaging computer HP xw6000 and a National Instruments PCI-1424 frame grabber. It's said in the article that "the software was written in ANCI C for portability". Is that a typo, or does there exist such a beast, compromising the C standard somehow? (This was the only occurrence of where the acronym ANCI was mentioned in the article, there is no mention of ANSI.) The system is basically a DSL 3-D imaging system, but I cannot see how it would have been possible to create such a program in ANSI C, either.

Maybe Mr. Kirby could elaborate on that?
