Question about -Widentifier-case - Gpc

24 Jan 2006


      I have a question on the meaning of the identifier-case warning in gpc 
(gpc345u2 on Mac OS 10.4.4). Compiling the program below I get three 
warnings but I'd expect none since in all three cases the two referenced 
variables are different.
Is my expectation wrong?
Best regards, Peter
{ 1} program cap;
{ 2} { compile with gpc -o cap -Widentifier-case cap.pas }
{ 3}
{ 4} procedure p(A: integer);
{ 5}
{ 6} 	procedure q(a: integer);
{ cap.pas:6: warning: capitalisation of identifier `a' doesn't match }
{ 8} { cap.pas:4: warning:  previous capitalisation `A' }
{ 9} 		begin
{10} 			a := 1;
{11} 		end;
{12}
{13} 	begin { p }
{14} 		A := 0;
{ cap.pas:14: warning: capitalisation of identifier `A' doesn't match }
{16} { cap.pas:6: warning:  previous capitalisation `a' }
{17} 	end;
{18}
{19} procedure r(a: integer);
{ cap.pas:19: warning: capitalisation of identifier `a' doesn't match }
{21} { cap.pas:14: warning:  previous capitalisation `A' }
{22} 	begin
{23} 		a := 1;
{24} 	end;
{25}
{26} begin
{27} end.
