Some deprecation warnings fail the build with -Werror flag, even if annotated with @nowarn

[flindskog]

Compiler version

3.3.0

Minimized code

import scala.annotation.nowarn
object Foo {
  private def bar[T](body: => T): T = body

  def foo(): String = bar {
    @nowarn("cat=deprecation")
    val m = implicitly[Manifest[String]]
    m.runtimeClass.getName
  }
}

Output

The code fails to build when compiling with the scalac flag -Werror.

Expectation

Expect the code to compile, since the deprecation warning is suppressed.
