The TRIM option causes output files to be written without a newline on 
the final line, which upsets software that cares about such things.  
We are generating C/C++ code from templates and g++ complains - I 
understand a C++ source with incomplete final line can cause undefined 
behaviour according to the standards.

To reproduce, please see the attached program, which runs itself 
through Template::process, and check the output.

test.pl:

#! /usr/bin/perl -w

use strict;

use Template;

# Create a template processor.
#
my $config = {'INCLUDE_PATH' => ".",
	      'OUTPUT_PATH'  => ".",
	      'TRIM'         => 1,
	      };
my $tt = Template->new($config)
  or die "Failed to create template processor: $Template::ERROR";

# Process the source template, to generate the output.
$tt->process($0,
	     { },
	     "$0.out")
  or die "Failed to process template foo: " . $tt->error();

You could probably make use of an empty [% %] statement with prudent use of [% -%] to make the end line show up. I'd need to see your template though to be sure.

you could also read in $0 and add a new line manually.

I think the only answer I can give here is don't use TRIM. If you have a good reason that you need TRIM, let me know.
