hi gcc-patches, as part of pinging, i'll explain the story of this patch.
I want to make sure all netbsd archs work with upstream gcc. in this case, netbsd/arm's EABI support. I try to break up my changes into digestible chunks that are rational, which is why this change came first. building netbsd/arm gcc-trunk, I had a build error in libstdc++, because this stddef.h relies on include guards: #if defined(_ANSI_H_) || defined(_MACHINE_ANSI_H_) || defined(_X86_64_ANSI_H_) || defined(_I386_ANSI_H_) In theory I could have just added: || _ARM_ANSI_H_ this felt gross, so I tried a better solution. the file even comes with comments like: /* Why is this file so hard to maintain properly? so I try my best to help. Please let me upstream local changes. there are a lot of them. and I feel unable to get them across. I have so many changes that it feels inappropriate to ask for help with hard problems like internal compiler errors because upstream GCC hit a different problem. I'm not familiar with stuff so this is hard :-(
