The error is this: --8<---------------cut here---------------start------------->8--- Failed test 346 - NaN sprintf %a is NaN at op/infnan.t line 303 # got "0x1.8p-1" # expected "NaN" --8<---------------cut here---------------end--------------->8--- It _is_ definitely related to defining _GNU_SOURCE, so hopefully that gives a clue as to where it's happening. I've just switched the second machine back to Cygwin 2.4.1 to see if it was somehow one of the newlib changes in 2.5.0, but it's not. I have no idea yet how _GNU_SOURCE figures into the issue, only that Perl sprintf is a big hairball of workarounds for various system implementations (and for the test in question involving %a format probably doesn't even use the system/newlib sprintf). I've ran out of time, I will build without _GNU_SOURCE again tomorrow and see if that produces any differences in config.h that are notable.
