Yes:

-lSDL -lpthread

I presume I run this like so ?

gcc -E -ansi -Wall lesson04.c -o lesson04.out  -lGL -lGLU `sdl-config
--cflags --libs`

The resulting two lesson04.out files are exactly the same. I can send a

Yes:

$ file lesson04
lesson04: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.2.0, dynamically linked (uses shared libs), not stripped

$ file lesson04.good 
lesson04.good: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),
for GNU/Linux 2.2.0, dynamically linked (uses shared libs), not stripped
