Date: Wed, 13 Oct 2004 17:00:58 -0500 From: Jonathan Atkins Subject: [Fwd: Re: SDL_image on Solaris x86 help please] apparently __i386__ is insufficient for Suns C Workshop compilers... so a sun x86 user told me about this...and tested his own solution. I think it wouldn't be a bad idea to add __i386 to the SDL_byteorder.h so that it works for that compiler.
