Interesting. This means that in the quadruples
CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM
the kernel is not so important (because of (a)), and that instead it would
be more useful to have a simple test for glibc systems. Which neither the
previous naming scheme
linux-gnulibc[15] [Linux libc5] -> no
linux-gnu -> yes
gnu [Hurd] -> yes
nor your advocated naming scheme
netbsd*-gnu) -> no
netbsd*) -> no
knetbsd*-gnu) -> yes
kfreebsd*-gnu) -> yes
gives.
IMO, we should either
- move the AM_GLIBC macro (gnulib/m4/glibc.m4) into autoconf, so that
more packages use it instead of making choices based on config.guess
results when all they need is AC_GLIBC, or
- ask RMS to include the libc type in a canonical quadruple/quintuple.
