Adding to my includes

[T. Horton]

Hello;

	I'm very new to C and GCC (though I've coded in Java, Delphi,
etc).  I'm not sure how the pathing works in GCC when I add headers to a
sub directory in my include directory.  I think I can use -L command
line option (like -c in java).  Though what I'm more looking at is how
to permanently add to the pathing (like using CLASSPATH with Java).

Thank you,
Tim
