Build issues

[ktm5j]

Hi! Sorry to open a new issue before following up on the first one, but I'm having trouble building my project.

I've been using the ~master branch of this repo because of features that are missing from v0.0.1. But I've just noticed that d++ is outputting some error text into source/symmetry/api/libzfs_core.d that probably shouldn't be there.

I encountered this issue while trying to build under Ubuntu 19.04. Originally I couldn't build at all because this error text was placed into a code block. I've been missing this when building under Voidlinux because the text was placed into a comment block. Here's what I'm seeing:

string[string] zfsInheritProperties(string name, string[string] args)
{
 return zfsIoctl(ZFS_IOC_SNAPSHOT_LIST_NEXT,name,args);
}

I think the difference in where the error text is placed has to do with the version of gcc that d++ was built with. I think the version of llvm/clang also has some impact, but I haven't been able to determine any pattern. However I'm more sure about gcc-7 vs gcc-8 being a factor.

It looks like the real issue here is in d++ encountering errors while your preGenerateCommands are being run. There's some place in libzfs_core.dpp that's being interpreted as code instead of a comment.

If you know of a quick way to fix this I would be eternally grateful! Otherwise I'll see if I can find the root of the problem, but it will probably take me a while
