[ITJamie]

this fix worked for us to parse out hundreds of includes which had comments at the end of them

[omoerbeek]

I'm not sure semicolon inside a quoted path will now work as expected.

I think it would be better to fix the splitting of tokens. This also should fix the parsing of the other $XYZ cases.

[omoerbeek]

It looks like correct comment handling would require quite a bit of effort, e.g. things like quoted pathname with semicolons or spaces in them go wrong as well. Given that, your PR might be acceptable.
