@ianlancetaylor requested issue #38408 to be considered for backport to the next 1.14 minor release.

@gopherbot Please add issue for backport to Go 1.14.

This is an incompatible change to how cgo handles anonymous structs. There is no workaround for people using C headers that use the construct that changed incompatibly. We should fix this in the 1.14 branch.
