Someone using linux said I should try linking with these
x-libraries: -lXi -lXmu -lm -lXext -lX11, so I issued:
$ gcc -Wall -o test
test.c -L/usr/local/lib -lGL -lGLU -lglut -L/usr/X11R6/lib -lXi
 -lXmu -lm -lXext -lX11

That yields a great number of errors (listed last).

When I installed cygwin, I made sure I installed the X libraries. Maybe I am
specifying the path wrong, or I should use other names, or I haven't
installed what I need (if I haven't done that, I wouldn't know what more to
install =().
