Subject: Allow build on unsupported GOOS (#424)
X-Git-Tag: v1.7.2~124
X-Git-Url: https://go.fuhry.dev/?a=commitdiff_plain;h=bfa0135e7e7333f9552eac2ddd8771f31e818610;p=fsnotify.git

Allow build on unsupported GOOS (#424)

In cases where fsnotify is a transitive dependency of a package, it
might need to be built on platforms not supported (yet), e.g. aix.
Provide an empty implemention for these cases, so depending packages
don't need to add workarounds.

Replaces #314
