This changes TARGET_WNOHANG to be a member of an enum, rather than a define, and also adds a DEF_ENUM_FLAGS_TYPE for this type. Then, it changes target_wait and the various target wait methods to use this type rather than "int". This didn't catch any bugs, but it seems like a decent cleanup nevertheless. I did not change deprecated_target_wait_hook, since that's only used out-of-tree (by Insight), and there didn't seem to be a need. I can't build some of these targets, so I modified them on a best-effort basis. I don't think this patch should go in before the release branch is made. gdb/ChangeLog 2020-09-18 Tom Tromey <tromey@adacore.com> * windows-nat.c (struct windows_nat_target) <wait>: Update.
