autoconf-2.50 feedback

[Bruno Haible]

Hi,

My general impressions after 1 day of autoconf 2.50 use.

- The backtrace facility is really a nice feature.

- "config.status much faster on most architectures"
  but configure is slower. Here are the timings of gettext's configure:

    autoconf 2.13:   23.0 sec real   14.2 sec user
    autoconf 2.50:   24.5 sec real   14.8 sec user

  So you are not following Moore's law that programs should get twice as
  slow every 18 months, in order to compensate the increase in CPU speed
  in the same time :-)

- Why is the @host_alias@ Makefile variable not set any more? It is still
  documented.
