Hi Hilko, please find attached a patch fixing this bug.
Cheer, Sven
Description: Fix passing argument 4 of ReadFile from incompatible pointer type ReadFile returns the number of read bytes in a DWORD, i.e. unsigned long, not in an int. Mangle returned value into an int when it is used with calling output(), it cannot be greater than 1023 (= 0x3FF) anyway.
