-// Reason: This test is `ignore-windows` because the `no_std` test (using `#[link(name = "c")])`

 //@ ignore-windows
+// Reason:
+// - MSVC targets really need to parse the .pdb file (aka the debug information).
+//   On Windows there's an API for that (dbghelp) which maybe we can use
+// - MinGW targets have a lot of symbols included in their runtime which we can't avoid.
+//   We would need to make the symbols we're looking for more specific for this test to work.
