10# Before building our test main.go, ensure that an up-to-date copy of
11# runtime/cgo is present in the cache. If it isn't, the 'go build' step below
12# will fail with "can't open import". See golang.org/issue/29004.

14# (The fix in golang.org/issue/29004 didn't completely fix the underlying issue:
15# cmd/go/internal/load adds a bunch of implicit dependencies
16# based on various heuristics, and, due to a bug described in
17# https://golang.org/issue/31544#issuecomment-490607180,
18# those implicit dependencies are not added early enough during
19# loading to properly affect the import graph.)
