[Debian-med-packaging] Help with C++ needed

[Patrick Baggett]

Hi Andreas,

I'm pretty decent at C++. The lines 120 and 134 contain the same function
prototype, i.e. the return value is the same, the name is the same, and the
parameter count/type/number are the same. The compiler cannot tell which
version of the function to use. I can't access the git repo via http for
some reason, but this has been illegal in C++ since the start, so it's not
just "old code, new compiler" sort of problem. Check to see if there are
conditional compilations around these function definitions.

Patrick
