>Description:
When multiple functions with the same name but different parameters are specified the best match is not always selected.  See attached code and How-To-Repeat...
>How-To-Repeat:
Compile this and you'll get an error like:

output.cc: In function `int main ()':
output.cc:365: warning: passing negative value `-100000000' for 
argument 1 of `CLatitude::CLatitude (unsigned int, unsigned int, 
unsigned int, bool)'

That means it's matching it with the wrong function, it should be matching it with CLatitude::CLatitude (int, int, int, const string&)
>Fix:
If you put string("N") instead of "N" and so on, it matches it properly.
