Possible fix

Build fails probably due to overflow in Math-Int64.t with:
.
.
.
+ make test
PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-MTest::Harness"
"-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')"
t/*.t
t/as_int64.t ............ ok
t/die_on_overflow.t ..... ok
t/Math-Int64-Native.t ... ok
#   Failed test 'max int64 >> 63'
#   at t/Math-Int64.t line 183.
#          got: '0'
#     expected: '1'
#   Failed test 'max int64 >>= 63'
#   at t/Math-Int64.t line 187.
#          got: '0'
#     expected: '1'
# Looks like you failed 2 tests of 1139.
t/Math-Int64.t .......... 
Dubious, test returned 2 (wstat 512, 0x200)
Failed 2/1139 subtests 
t/Math-UInt64-Native.t .. ok
t/Math-UInt64.t ......... ok
t/MSC.t ................. ok
t/pods.t ................ skipped: Only the author needs to check that POD docs
are right

Test Summary Report
-------------------
t/Math-Int64.t        (Wstat: 512 Tests: 1139 Failed: 2)
  Failed tests:  1138-1139
  Non-zero exit status: 2
Files=10, Tests=2511,  0 wallclock secs ( 0.14 usr  0.01 sys +  0.33 cusr  0.02

Result: FAIL
.

.

Using int64 in ipow sub-routine seems to make test pass. In attachment is patch
with this change. Could you please review this patch and forward it to upstream
if correct.
