Ok, what the heck does this mean!!!??? (gpc-970624)

trunkuti.pas: In function `Dectobin': trunkuti.pas:332: prior parameter's size depends on `Decinput' make.exe: *** [trunkuti.o] Error 1

This is the offending line (I don't think I can send the whole file for as I think it's confidential)

function DecToBin( DecInput : string ) : wrkstring;

Ancient borland legacy code I'm trying to port to gpc (comiled with 2.0).

BTW thanks for the great work, most of the problems I had using 2.0 have gone!!
