Re: cross compiling --error when autoconf

Hello Hema K,

thanks.  This description of your problem is much better than the
other ones.  (I apologize that I have missed this yesterday.)

You should be able to do this without any change to mutt's
configure script, just by specifying the right --host.
Please read the node "Specifying Names".

So my general impression is that it was mistake to touch
configure.in.

Anyway:

In the manual for autoconf-2.59, you can find that both
AC_CANONICAL_SYSTEM and AC_TRY_RUN are obsolete.
And the AC_CANONICAL_TARGET macro corresponds to --target option,
which you shouldn't use here; see the node mentioned above.

The nodes "Obsolete Macros" and "Run Time" explain what to do
instead of AC_TRY_RUN.

And I don't think you should run "autoupdate" here.  The configure.in
is usable as it is.
