Reason for 11 or 1.1 appended to SDL files?

[Dmitry Marakasov]

Hi!

I wonder what is the reason SDL has it's version appended everywhere
(include/SDL11 instead of include/SDL, libSDL-1.1.so instead of
libSDL.so, sdl11-config instead of sdl-config). It takes extra time when
porting SDL software, extra patches need to be added. Is there any good
reason for such changes to sdl' file names?
