[fpc-pascal] Illeagal assignment to For Loop variable in Free pascal

[Jim Leonard]

The error is because FreePascal optimizes loops wherever it can, and 
trying to modify the loop variable would break under that optimization.

While you could enable compilation flags to make things more TP 
compatible, looking at the code, I can see that the 'counter:=1' is just 
an early termination clause.  If the variable 'counter' isn't needed 
after that section, you could replace that line with 'break' which would 
exit the loop immediately (which is what the code does now).
