+// This is required since some frameworks need TLS setup the C way which Go doesn't do.

+// Even if CGO_ENABLED=1 the Cgo runtime is not imported unless `import "C"` is used.
+// which will import this package automatically. Normally this isn't an issue since it
+// usually isn't possible to call into C without using that import. However, with purego
+// it is since we don't use `import "C"`!
