Since pclose (Unix) returns signed int and GetExitCodeProcess (Windows)
returns unsigned DWORD, and then result is compared with -1 in common
branch, now I don't see clean way to get rid of the warning in this mix
of conditional compilation branches. Let's leave as it is now.

There is similar mix of signed/unsigned in ForkedCalls.cpp (setRetValue
call) but without compiler warnings.
