How would people feel about adding a configure option --with-implicit-extern-c? Then we could justifiably flip the default for the generic *-elf, etc., targets. In fact in general we could then take the macro out of the tm.h files and into config.gcc, which is probably a more reliable place to put it anyhow. Ian
