I did run into the same problems on the "Enigma" project 
(http://www.nongnu.org/enigma). Every OS had need of another SDL 
handling and even the different Windows versions did prove to be 
incompatible (XP is an exception, 95,98, 2000, Vista are the same)

You will find the handling for Linux, all Windows, Mac OS X in the file:

http://svn.berlios.de/wsvn/enigma-game/trunk/src/video.cc

(Sorry this file would need some cleanup)

The main comment I added last year to the sources:

// Set the caption icon -- due to SDL doc it has to be set before first 
SDL_SetVideoMode() !!
// In praxis this SetIcon does not work for Linux, nor is it necessary 
for OSX.
// Just XP with selected "WindowsXP Design" needs this SetIcon.
// See video::Init() for icon set for Linux and other Windows versions
// Mac icon is set via Makefile


I would really appreciate a simple unified SDL handling of this problem.

Greets,
