could powerpc-gekko-cpp define GEKKO by default?

[zimage]

When I run cpp on a linux system, __linux, __linux__, and linux are all defined automatically

Code: Select all

$ touch /tmp/foo.c && cpp -E -dM /tmp/foo.c | grep linux
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define linux 1

On my mac they define __APPLE__

Code: Select all

$ touch /tmp/foo.c && cpp -E -dM /tmp/foo.c | grep APPLE
#define __APPLE_CC__ 5370
#define __APPLE__ 1

Could this be done with GEKKO being defined in powerpc-gekko-cpp? If someone could point me to the gcc source for devkitPPC, I'd be happy to supply a patch.

Cheers,

When compilling for Wii, the define "GEKKO" will be used.
It's passed directly to the compiler (-DGEKKO) when running make.

See Wii make rules files : "path to your devkitPPC"/wii_rules

Yes, I know that. Software that has been written for platforms other than the wii doesn't include $DEVKITPPC/wii_rules in their Makefile though. It would be nice if cpp defined this automagicaly. I know, I could "export CPPFLAGS=-DGEKKO" before running "./configure --host=powerpc-gekko", but having it defined by cpp seems cleaner, since this define is what everyone seems to be using in the wii comunity. I just thought it would make porting and other things more convenient.

I just looked at the patch to gcc and noticed that "__wii__" is defined when you use "cpp -mrvl". This is exactly what I'm looking for.
