The language being used to rewrite the MOC software at JSC is C++, not C.
The language selection was made back in 1993. The selection came down to
either C++ or ADA with a dialect/preproccesor called Dragoon.  The rationale 
for selecting C++ is all documented in a report to NASA by the 
ROSE (Reusable Objects Software Environment) project.  
Last time I checked, there were 80+ developers and
support staff from Rockwell, UNISYS, Loral, Barrios,and NASA
working on getting a legacy body of software 
( >2.5 million SLOC) rehosted to C++ on a network of CDC/DEC/Sun workstations.
I was a member of ROSE until May 1995.
