          Issue ID: 15856
           Summary: Confusing error message with -transition=checkimports
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: doob at me.com

Compiling the following code:

class Foo
{
    import core.stdc.config;

    struct Bar
    {
        c_long a; // line 7
    }
}

With the -transition=checkimports flag the compiler gives the following error
messages:

main.d(1): Deprecation: class main.Foo alias core.stdc.config.c_long found in
local import
main.d(7): Deprecation: local import search method found nothing (null) instead
of alias core.stdc.config.c_long

I'm not sure if the error message is just bad or if there's a bug in the
compiler.
