Personally, at least for the time being, we don't care about HOST: as
said by Pavel, only specific packages will need it, and they certainly
need it so badly that they already perform their tests.  And if they
don't, the simple fact that Autoconf supports some HOST-path-sep test
will not make these package HOST-path-sep aware.

So let's drop this.

But BUILD-path-sep *does* matter, and will be a significant win.

Could you describe precisely how it works?  In fact, may I ask you to
complete the documentation of PATH in autoconf.texi to explain how it
works on Cygwin and DJGPP?  Maybe Earnie would have good hints to

Because I seem to have understood we kinda can have ; or : as a PATH
sep on Cygwin.  But then, the test suggested above might not be right,
since we will have to adjust ourselves to the choice made by the
user.  Autoconf by itself does not care extending PATH, it wants to be
able *split* it.

Hm, let them be in AS_, forget Autoconf.

PS/ Could you also add some doc about COMSPEC etc. in autoconf.texi?
You're currently burned for code, but documenting is OK :)
