Libguestfs - Aug 2009 - [PATCH libguestfs] build: daemon/do_debug: parameters aren't always unused

Thanks to the reminder from Dan Berrange,
here's a patch to make build output less verbose, by default.
E.g., instead of the redundant multi-line compilation/linking commands,
you'll see something like this by default:

  CC     guestfsd-fsck.o
  CC     guestfsd-grep.o
  CC     guestfsd-grub.o
  CC     guestfsd-glob.o
  CC     guestfsd-guestfsd.o
  CC     guestfsd-headtail.o
  CC     guestfsd-hexdump.o
  CC     guestfsd-initrd.o
  CC     guestfsd-inotify.o
  ...
  CC     guestfsd-zero.o
  CC     guestfsd-zerofree.o
  CCLD   guestfsd

If you want to diagnose a problem, or just prefer to see
full commands, build with "make V=1".

Subject: [PATCH libguestfs] build: enable automake's silent rules option

* configure.ac: Use AM_SILENT_RULES([yes]).
Those who want verbose build output may configure with
--disable-silent-rules or use "make V=1".
* daemon/configure.ac: Likewise.

I tried this one before but it doesn't work on RHEL 5.3:

aclocal:configure.ac:27: warning: macro `AM_SILENT_RULES' not found in
library
libtoolize: `config.guess' exists: use `--force' to overwrite
libtoolize: `config.sub' exists: use `--force' to overwrite
libtoolize: `ltmain.sh' exists: use `--force' to overwrite
aclocal:configure.ac:27: warning: macro `AM_SILENT_RULES' not found in
library
configure.ac:27: error: possibly undefined macro: AM_SILENT_RULES
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1

(There was another one I wanted to add to do with colouring
error messages, that also doesn't work on RHEL 5).

Rich.
