How can one find such a thing himself without trial&error?

Some time ago I had a similar problem with "bool DeleteFile(PChar)" function in Windows API and sysutils function "DeleteFile(string):boolean".

"Good" program:
uses windows,sysutils;
const B:shortstring='1.txt';
begin DeleteFile(B); end.

"Bad" program: // Error: PChar expected
uses sysutils,windows;
const B:shortstring='1.txt';
begin DeleteFile(B); end.

While compiler gives a hint about "true" declaration, it does not point to the problematic unit.
