Describe the problem

A sketch containing a function that makes use of a type created with typedef does not compile under certain circumstances. This issue may be related to bug #1785.

To reproduce

When the following sketch is compiled,

void somefunction() {}
typedef int myInt;
void myTest(myInt) {}

void setup() {}
void loop() {}

this error is raised:

.../x.ino:3:18: error: variable or field 'myTest' declared void
 void myTest(myInt) {}
                  ^
.../x.ino:3:13: error: 'myInt' was not declared in this scope
 void myTest(myInt) {}
             ^~~~~

When the first two lines are swapped, the sketch compiles fine.

typedef int myInt;
void somefunction() {}
// ...

Expected behavior

Both sketches are expected to compile. For reference, the following code compiles without any errors or warnings

void somefunction() {}
typedef int myInt;
void myTest(myInt) {}

int main() {
  return 0;
}

with the following command:

g++ -std=c++11 -Wall -Wextra -pedantic x.cc
