What exactly does that mean ? 

I'd guess you are saying that compare() is a standard C++ library
function, except GCC doesn't include all the standard variations, such
as :
int compare(size_type pos1, size_type n1, const basic_string& str)
const; 
but includes other versions, which arent standard, such as:
int compare(const basic_string& str, size_type n1,)

Well its not so obvious to me.:)
Let me see if I got this straight
He's using this  form of compare:  
if (( pos3 > 0 ) && (word.compare(ies, pos3)))  

which would match:
int compare(const basic_string& str, size_type n1,)  

Which does not match any compare() function in standard c++ but is
included with djgpp. 

Correct ? 
As you can tell I'm just learning how to understand the prototypes cited
in the error messages and the documentation, so I really would like to
know if I finally am getting it right. 

Red    
If this is right, maybe it means I finaly can follow those long, cryptic
error messages I get when there's no matching function.
