reduced test case (see moduleB import)

>From forum: http://forum.dlang.org/thread/causshkknlxqlbqrbnkv@forum.dlang.org

OS: Windows 7 (32 bit)
DMD: 2.069.2 and 2.070.0-b1
RDMD: build 20160103

Problem: import inside function produced linker error then -g switch used.
Test files in attach:

moduleA.d
test\moduleB.d
test\moduleC.d

/////////////
module moduleA;

public void funcA () {
  import test.moduleB: funcB;
  return;
}

void main(string[] args) {
  return;
}

/////////////
module test.moduleB;

//import test.moduleC: funcC;  //this works

public void funcB () {
  import test.moduleC: funcC;  //linker error
  funcC();

  return;
}

/////////////
module test.moduleC;

public void funcC () {
  return;
}

/////////////


C:\dmd2\windows\bin\rdmd.exe moduleA.d
//no errors, moduleA.exe created


C:\dmd2\windows\bin\rdmd.exe -g moduleA.d

Problem disappear, then i move import in test.modileB to global level:

/////////////
module test.moduleB;

import test.moduleC: funcC;  //this works

public void funcB () {
  //import test.moduleC: funcC;  //linker error
  funcC();

  return;
}
/////////////
