GDB is more aggressive: https://sourceware.org/gdb/wiki/Internals%20Obsoleting-code For Solaris, I believe it's been a while that the only maintenance we've seen comes from you. Which kind of makes you the de-facto maintainer. :-) Since gcc obsoleted Solaris 9 years ago, and nobody all these years stepped forward, I think we should be able to just drop it. I think you've proposed this in the past, even. I very much doubt anyone would step forward this time. > Does gdb go for immediate removal instead?
