Well... I would have but I don't have a patch :).
Anyway, it's not clear that the entire problem is config.guess, here.

Right; that's kind of why I asked. It seems there are a few potential
solutions:
1) Have AC_CANONICAL_HOST require AC_PROG_CC, as Ossama suggested. One
problem here is that not all runs of config.guess _do_ require a C
compiler, and it's a minor drag that you can't use AC_CANONICAL_HOST
without a C compiler; couldn't we write a configure.in for some
system that _didn't_ need a C compiler? Or is that already right out?
2) Not require it, but change the recommended process, in the manual
etc., to encourage people to put AC_PROG_CC before AC_CANONICAL_HOST
if they're going to use it.
3) Have config.guess print a more reasonable error message if it needs
a compiler and can't find one; it should try to build the most
trivial test program possible, like "int main() { return 0; }", and
link and run it; if it doesn't work print something like "can't find
a working C compiler; set HOST_CC to a working compiler, or provide
a valid host specifier to configure". Or whatever.
Oh yeah, and it'd be nice if it didn't throw the error output from
the compile on the floor, so it'd be simpler to see what went wrong.
And, of course, it'd be extra-nice if we didn't need to make this
test until/unless config.guess knows it needs a compiler.
Too bad we can't use shell functions :( :( :( :(
Anyway, it seems like one of 1 or 2, plus 3, would be a good combination.
