5.10.1-RC1 Test::Harness ruins @INC

Hi,

I'm on Win32 (Windows XP). Below my sig is the output of 'perl -V' for this 
(5.10.1-RC1) build of perl.

Let's start with a simple test script (inc.pl):

#############################
use warnings;

print "1..1\n";

print STDERR "\nINC: $_" for @INC;
print STDERR "\n\n";

print "ok 1\n";
#############################

No problems with that - it outputs:

#############################
C:\>perl inc.pl
1..1

INC: C:/perl510_M/5.10.1/lib
INC: C:/perl510_M/site/5.10.1/lib
INC: C:/perl510_M/site/lib
INC: .

ok 1

C:\>
#############################

This is as expected - the @INC is identical to that reported by 'perl -V'.

However, if I run that test script via Test::Harness::runtests() the output 
changes quite markedly:

#############################
C:\>perl -MTest::Harness -e "runtests('inc.pl')"
inc.pl ..
INC: C:/PERL51~1/510~1.1/lib
INC: .

inc.pl .. ok
All tests successful.
Files=1, Tests=1,  0 wallclock secs ( 0.08 usr +  0.00 sys =  0.08 CPU)
Result: PASS

C:\>
#############################

Most notably, 2 of the @INC directories (C:/perl510_M/site/5.10.1/lib and 
C:/perl510_M/site/lib) have been lost.
Therefore, any test script that needs to load a module that has been 
installed into one of those missing @INC locations crashes during 'make 
test'.
(Also, I notice we get the short pathname for C:/perl510_M/5.10.1/lib, but 
that in itself is not a problem.)

I haven't yet tracked down the cause of the problem (which seems to arise 
*only* when I build a "versioned" perl).
Can someone here suggest a likely place to find the cause ?

Cheers,
Rob
