[fpc-pascal] FPC 2.6.2 for DOS/Go32V2 FP.EXE cannot run a second time

OK, with FPC.ZIP dated 5.10.2013 I have translated successfully FP.EXE
and it works. I tested only FP.EXE, not RTL units.
It seems that the error (FP.EXE cannot run) was corrected.
Thank you for your help.
Expected question: when the new version 2.6.3 will be available?
