Why not have a configure-time test to figure out the byte order? (at
least for all “configure” platforms)
Because that may not work when cross-compiling SDL to another platform (as
I am in this case), unless you add specific configure.in conditionals for
every architecture you support. To me that seems a lot more cumbersome
than just adding a single line to this header file. Especially since I’m
cross-compiling to an SuperH Linux target, why would you add configure
options for each supported Linux, NetBSD, etc. target, when the compiler
can efficiently handle it at build time?
Since Sam has it all in SDL_byteorder.h, the addition of a new architecture is
as simple as adding a condition for it’s arch. identifer, e.g. sh,
mips, and it’s endianness.

Because it doesn’t work for non-configure platforms.
