Don't specify the C runtime libraries, they are implied and adding
them here can only do harm.  IOW drop "-lm -lc".

Same with C runtime header directories.  Drop "-I/usr/include".

The compiler is irritated because you specified the redundant
"-I/usr/include" in your CFLAGS above.

The next warnings are because the linker examines the libraries from
left to right *once* only, therefore the order of your "-l" options
matters.

Says that libXaw.a reference a symbol that is probably in libXpm.a.
So you need to have -lXaw *before* -lXpm.

Similar problems with -lXt and -lSM, I guess.
