perl-framework/Apache-Test Changes
Log:
Use function prototypes in Apache::TestUtil functions t_cmp() and
t_is_equal() to handle the case when an argument to the function, is a
function call itself which may return undef (previously had to
explicitly force a scalar context to get the undef value). The idea
was borrowed from Test::More.

-When comparing to a return value from a function, that may return an
-C<undef> value, there is a catch -- in the list context the C<undef>
-value disappears and you end up comparing with the next argument.
-Therefore you can either explicitly call the function prior to
-comparison:
-
- my $received = foo();
- t_cmp($expected, $received, "may return undef")
-
-or use a scalar context:
-
- t_cmp($expected, scalar foo(), "may return undef")
This function is exported by default.

Fixed a Windows-only segment which would result in a
'use of uninitialised value' error if a hash being traversed
had an entry with a key but an undefined value. [Ken]
