cos() test fails (with -Duselongdouble perl)

[eserte]

The test suite fails on some of my systems:

#   Failed test 'cos($angle1) = 0 (overloaded 'cos')'
#   at t/overload.t line 55.
#          got: '-0.0'
#     expected: '0.0'
# Looks like you failed 1 test of 40.
t/overload.t .. 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/40 subtests 

This seems to happen with perls compiled with -Duselongdouble (seen on linux & freebsd, both amd64/x86_64 and arm64).

Well that's ironic, I try to fix one failing test and end up creating another.
I'll wait for more results to come in then I will fix this and anything else that appears.
Thanks
