The other ones suck. The root cause is that enum_field (enabling enum bitfields, a non-ISO C extension[1]) is used only on GNU C. It is perfectly supported by the irix compiler I use. So that should be tested in configure. Martin, do you want to do it or should I hack up something? OG. PS: gdb 4.17 has just been released. Happy hacking. [1] At least for the first version of ISO C. I don't know since then.
