# Issue 52863.

# We manually create a .syso and a .a file in package a,
# such that the .syso file only works when linked against the .a file.
# Package a has #cgo LDFLAGS to make this happen.
#
# Package c imports package a, and uses cgo itself.
# The generation of the _cgo_import.go for package c will fail,
# because it won't know that it has to link against a/libb.a
# (because we don't gather the #cgo LDFLAGS from all transitively
# imported packages).
