I'm also having parse errors. Two cases I found so far:
uint MILLION = 106; // does not understand the "" operator
uint month = 30 days; // does not understand the "days" unit;
I just tried with HONG code https://github.com/hongcoin/DO/blob/master/HongCoin.sol , share same problems.
Parse errors fixed w/solidity-parser v0.1.0. Please post further issues (such as rendering issues) in a separate issue. Thanks!
