You could do this:
require Test::Builder;
my $tb = Test::Builder->new;
$tb->output_even_if_compiling(1);
in the init code. Since Test::Builder is a singleton your settings
should stick.
Here's an interesting alternative. Do C<local $^C = 0> just before
running the tests, though that's pretty ugly.

Could you explain again why you need test output while compiling, I'm
not quite following. Assume you had the I_WANT_OUTPUT_DURING_COMPILE
environment variable could you show how you'd be using it?
