Parse error while parsing OpenZeppelin ERC20 contract

[dhilst]

I tried to parse the contract : https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC20/ERC20.sol

But I got this error

Fatal error: exception Solidity_exceptions.SyntaxError("Parse error", _)

I'm not sure if I'm doing something wrong, I'm using the 0.5.3 version of ocaml-solidity
