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! -Garrett
