native AmigaOS support by Diego Casorran

Diego Casorran's amiga build patch

ares configure and build fix

do the ares stuff in the configure file

Dominick Meglio made --enable-ares support an option =PATH to specify a
root path to an installed ares.

minor language fixes

Eric S. Raymond's fix of the NAME section

added some details from the old scrolls

removed old version checks

use the newer option names

updated 5.5 to use the modern names of these defines

ares in curl-config

removed one, added one

-lz fix

no need to add -lz to LDFLAGS manually, as AC_CHECK_LIB() does that
automatically!

updated

better human error message when a FTP response can't be read

curl-config now shows asyncdns if built with ares enabled

based on Gisle's comment, I removed the use of syslog() and fixed the
netdb.h include, then I re-indented some code to use curl-style

minor edit of the PRIVATE option

cut out the wrong version blurb

edited the -d section slightly

minor edit

VMS

Marty Kuhrt moved most of the VMS stuff to a separate header file.
