netbsd*-gnu: This triplet is being used by the system based on NetBSD's kernel
and libc with GNU userland.

freebsd*-gnu: This is an obsolete triplet. It used to be for system with
FreeBSD's kernel, Glibc and GNU userland, untill Richard asked me te rename
it to kfreebsd*-gnu.

kfreebsd*-gnu: This is the current triplet for Glibc-based GNU/KFreeBSD.

knetbsd*-gnu: Ditto for Glibc-based GNU/KNetBSD

Because kfreebsd*-gnu and knetbsd*-gnu match the GNU/* rule below:

[ check for netbsd*-gnu ]

[ kfreebsd*-gnu. this check is only for compatibility ]

[ match both kfreebsd*-gnu and knetbsd*-gnu ]

If I had to explain all the history of events, it'd take me a lot of time to
sort it out (which i don't have). Please tell me what you want to know exactly.
If you want something to put in comment for host-os.m4, I suggest:

#1 netbsd*-gnu: NetBSD's kernel and libc with GNU userland.
#2 knetbsd*-gnu: NetBSD's kernel with GNU libc and userland.
#3 kfreebsd*-gnu: FreeBSD's kernel with GNU libc and userland.

As for the system names of #2 and #3, they're GNU/KNetBSD and GNU/KFreeBSD

I won't pronounce myself on the system name of #1. All I have to say is Richard
probably wants it "GNU/KNetBSD" either [1], and that if you want to discuss it
with the netbsd*-gnu people you can reach them at address@hidden
