Bug #11840

Updated by nobu (Nobuyoshi Nakada) over 4 years ago

Encouraged by Hiroshi Shibata's talk at Ruby Kaigi 2015, I tried "make check" on my usual cygwin compilation. If I understand the output below correctly, there was only one error in 1010 tests. If we can fix that error (or exclude the test if it doesn't make sense on cygwin or on Windows in general), then cygwin would pass the tests.
