linking surprise...

[Christian Henz <chrhenz@gmx.de>]

I compiled some SDL+OpenGL code with both gcc/linux and mingw. With 
mingw, the stripped exe would be < 10KB, while the linux binary was 
~40KB (5K and 18K upx'ed). Since I want to port a 64K intro to linux, 
this bothered me and I thought, maybe I'd better use glut than SDL.
 
So i added -lglut to my linker switches just to see how much that would 
add to the size of the binary... surpsisingly the resulting filesize was 
only a fraction of the original one! How can this be?  


# gcc -o timing main.o timer.o process.o -L../basecode_gl -lbasecode_gl 
-lGL -lGLU -lm `sdl-config --libs`
# ls -l timing
-rwxr-xr-x    1 chrissi  chrissi    177638 2002-10-23 03:13 timing
# strip timing
# ls -l timing
-rwxr-xr-x    1 chrissi  chrissi     42072 2002-10-23 03:13 timing


# gcc -o timing main.o timer.o process.o -L../basecode_gl -lbasecode_gl
