autodie 1.10_05

on Perl CPAN

Kludgy support for Perl 5.8 using Scope::Guard and dark
and terrible magicks taken from namespace::clean.

Rudimentary caching of generated code, to avoid having
to regenerate the same code every single time Fatal/autodie
is used on the same function.

Nuking subroutines at end of lexical scope moved into
own subroutine.

Perl 5.8 support working! Backcompat mode not yet
supported, nor is autodie with user defined subs.
The 5.8 support that is there is rather kludgy, and
still needs a lot of work.

Perl 5.8 code no longer gets executed under 5.10 when
executing write_invocation().

lex58.t tells the user that we'll get warnings under
Win32, and these are to be ignored. This is due to
a Perl behaviour where it always calls the shell under
Win32, even when multi-arg system is used.

lex58.t no longer fails to compile on Perl 5.10 which
is still clobbering exotic open. Perl 5.8 does not
clobber the exotic form.

Backcompat tests are all marked as TODO under perl 5.8

Makefile.PL moved back to saying autodie works under 5.8

Context/user-sub tests skipped under 5.8, which does
not yet support autodying of user subs.

lex58 tests now skipped if IPC::System::Simple not installed.

Squished a spurious warning from lex58.t
