I saw that fix.
On cygwin the old comment is true. cygwin perl supports no hugefloat
(long double),
but use64bitint, and perl Configure.pl --floatval='long double' fails in JIT.
src/jit/i386/core.jit:921:75: macro "emitm_fldt" requires 6
arguments, but only 5 given
perl Configure.pl --floatval='long double' --jitcapable=0 passes.
But on various linux packages it works. I special cased cygwin in
mk_native_pbc,
also because of use64bitint.
