MinGW - Minimalist GNU for Windows

When I compile programs in MinGW, they dont print
messages in interactive mode with user. For example: I
compile sqlite. Then when I execute sqlite.exe cursor
goes first position in line but doesn't print anything.

Normal is that it write "SQLITE version...", etc, and a
prompt: "squilte>". I have confirmed that programs run
ok but without printing.

If I execute program out from Msys (in cmd for example)
it goes ok.

Of course, I've tryed with several programs and it is the
same effect.
