But maybe you should > define something like arm-freebsd-eabi in gcc's build configuration? Always a thing of extremes for me. I know Makefiles pretty darned well, both the BSD and teh GNU sort, but as well as I know them, that's how BADLY I misunderstand anything dealing with those configure scripts. I can't even begin to pick apart the code for those things. Irritates me, because if I find a problem in a makefile, I pop out an answer with the greatest of ease, but if it's well coded so that configure reruns itself immediately if there's any change in the makefile, then it has to run configure, and I'm basically utterly screwed. I like our BSD build system, not a configure script in sight! However, now that I understand that I can use arm-none-eabi, I am pretty sure I can do things, and the configure scripts in gcc aren't so well engineered to force me to deal with them like that. If I can deal with a configure script as a shell script, I can do that, it's dealing with it as m4 macros that leaves me cold.
