Bi-arch 64-bit/32-bit bug in *chflags(2) on NetBSD / standardizing *chflags(2)?

[Garrett Cooper <yanegomi%gmail.com@localhost>]

Hello NetBSD folks,
    I just ran into this issue today (variable length unsigned long
used in chflags syscalls) on FreeBSD and I wasn't sure if anyone was
aware of the issue yet on NetBSD [1] . Just wanted to let you guys
know so that maybe the 3 major BSDs could get on the same page as far
as definitions go to reduce external developer pain in other projects
like Python [2], etc (I chose to standardize on fflags_t for clarity
as it already appeared to have been standardized to some degree in the
FreeBSD sourcebase, but that appears to be a FreeBSD-specific
typedef).
    Please let me know if I need to redirect this message to an alternate list.
Thanks!
