[PATCH] 2.4.x:include/asm-i386/checksum.h GCC 3.X warning fixes

[Maksim Krasnyanskiy]

Marcelo,

Could you please apply patch below. It just fixes "multi line string" 
warnings.
2.5.X already has that fix. Patch is against 2.4.19-pre1.

btw People were complaining that GCC 3.0 is slower than 2.X.
3.1 seems to be as fast as 2.96. Compiled kernel size is about the same. 
And everything
works just fine on my dual Athlon box.

Patch URL (in case mailer messed up spaces)
         http://bluez.sf.net/checksum.h.patch.gz

Thanks
Max
