The best way is running this code snippet:
---------------------------------------------------
import std.compiler;
import std.stdio;
void main()
{
writefln("%s %s %s.%s (D%s)", name, vendor,
version_major,
version_minor, D_major);
}
---------------------------------------------------
You can also have a look at the std.compiler implementation if you want
to use the __VERSION__ and __VENDOR__ variables directly.

Yes, this is really a common problem. I'd say the simplest way to check
is trying to compile the code with the matching DMD version (e.g.
2.066.1).

Same reason. The old getopt code can't handle the help strings and
therefore produces these error messages. This works:
---------------------------------------------------
import std.getopt;
void main(string[] args)
{
bool time;
string fileIn;
string fileOut;
getopt(
args,
"time", &time,
"i|input", &fileIn,
"o|output", &fileOut
);
}
