Please show the code that declares Positive_count, and the calls of Line 
and Col, and explain in which file they are located, and whether those 
files (or the corresponding .ads files) contain any "use" context-clauses.

Showing the compiler's error message would also be helpful. Usually an 
ambiguity problem means that there are several different subprograms 
with the same name, and the compiler does not know which one you want to 
call, because the types of the parameters and the result are not 
sufficiently constraining, or because the call does not qualify the 
subprogram name with a package name.
