Trying out some more build options hasn't helped at all (debug builds hang just the same, and I see the same stack trace as Alex Gough reported; and builds without PERL_IMPLICIT_SYS also hang just the same), but unfortunately I've found another problem in the process :-(

It seems that win32/runenv.t fails tests 42-43 when perl is built with USE_IMP_SYS=undef (i.e. PERL_IMPLICIT_SYS is not defined, so there is no fork() emulation):

# Failed test 42 - expected number of elements in @INC for enough items so PERL5
LIB val is longer than 32k at win32/runenv.t line 246
#      got "2"
# expected "2051"
# Failed test 43 - expected elements in @INC for enough items so PERL5LIB val is
 longer than 32k at win32/runenv.t line 249
#      got "D:/temp/bleadperl/t/lib ."
# expected "zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz
[...]
zzzzzzzzzz zzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz D:/temp/bleadperl/t/lib ."

er than 32k
