Compiling a solidity library file with enum fails #349
Description
What happened?
Compilation failed (error below) when compiling a solidity file with imported enum as function parameters (enum declared in a separate library file)
EDIT: Compilation failed (error below) when compiling a solidity library file with enum as function parameter or return values.

Isolated Failing Code
Enum in function param
pragma solidity ^0.7.6;
library LibTest {
enum TestEnum {
A,
B,
C
}
function foobar(TestEnum test) public view {}
}
Enum in function return
pragma solidity ^0.7.6;
library LibTest {
enum TestEnum {
A,
B,
C
}
function foobar() public view returns (TestEnum test) {}
}
NOTE: Both of these works fine if it is a contract instead of library
Possible explanation
Might be caused by ethabi? There's a "similar" issue although for a different case: rust-ethereum/ethabi#75
