I think you have a simple type in front of you !

The optimazation switch is `-O' not `-o'. So you want - I think - the
and not `-os'. Otherwise you say the compiler to produce an object file
with the name `s', and therefore `make' is not satisfied, as it expects
file name `test2.out' ! It seems, gcc ignores the second `-o ....'.

Independent of the compiler build, yout `-os' should never work !
Otherwise - if it worked one day - the second `-o ....' has overridden
first one !

With friendly regards
