With my FreeBSD hat on, I think it would be fine to drop a.out support. FreeBSD still permits running a.out binaries, but if someone really wants to debug that they can probably grab an older snapshot of gdb if they really care. (FreeBSD has used ELF for binaries and cores since 3.0 which was released in October 1998. The last release to ship a.out binaries was 2.2.8 released in November of 1998.) -- John Baldwin
