schematics_parser.yy syntax error

[Uroc327]

Hi, I was about to have a look into qtflow a bit. When trying to build it, I got the following error:

Unfortunately I don't have any experience with flex/bison and also don't know, if those are actual problems for the project itself. Versions are 2.6.4 for flex and 3.3.2 for bison.

Yes, this solves the issue.

Good to hear the issue is solved. I've made a pull request #8.
