Well, it might not win Most Helpful Comment award, but istm the code is
wrong.  

A C++ compiler is under no obligation to support C99 code, and the C++
standard library supports afaict equivalent functionality in
std::numeric_limits (#include <limit>).  I'd patch the code and let the
KDE folks know.  

Just one man's opinion, of course, and perhaps I misunderstand.
