Let me be the first (maybe) to say this: welcome!
Recently, there appears to be several new people who aren't of english
origin, so don't worry.

Same here, Wordpad and make is all I need :).

First off, you shouldn't need the -L switch, so long as the libraries you
reference are in the /lib directory under where you installed all the MinGW
files.  GCC can determine the location of these libs relative to it's
install path.

Not quite the only difference.  Notice that in the first command line, you
placed you object (program.o) AFTER the libraries.  In the second one, you
placed it BEFORE all you directx libraries.  LD (the linker) IS sensitive to
the order of it's objects.  If program.o references symbols in libdsound.a
(et al), it must be written first on the command line.

Your English sounds pretty good!

Hope I helped :),
