I suppose it was necessary before when md-unwind-support.h didn't exist at build time, so dependency generation failed With the new scheme using AC_CONFIG_LINKS, they are indeed unnecessary. > Also a good start, though. Thanks for this work. Apart from those changes, the patch addresses the PowerPC Darwin and Windows32 issues as suggested: * rs6000/darwin-unwind.h is wrapped in !__LP64__, while removing the need for the !DARWIN_LIBSYSTEM_HAS_UNWIND test (only defined on Darwin 9 and up) by using the file only for PowerPC Darwin < 9. * i386/w32-unwind.h is wrapped in !__MINGW64__. Bootstrapped without regressions on i386-pc-solaris2.11. Ok for mainline? Thanks.
