Compile the following D program to find out:

-----
static assert(0, "Compiler language version: " ~ __VERSION__.stringof);
-----

I have this line in a file called langver.d, and whenever the exact
language version isn't obvious, I compile it to find out the version.
:-)  (And yes it deliberately asserts instead of using pragma(msg) so
that I don't have to type -o- or -of- or -c or whatever to suppress
actual code emission, just `$compiler langver.d`.)

Nice trick. Thanks. For the benefit of others, GDC 10 is based on 
DMD 2.076. https://dlang.org/changelog/2.076.0.html

Side note, Using $() is better than `` for subshells, as it makes 
nesting much easier. ;-)

Side note: Usually a lot of bug fixes are backported to GDC, so 
even though it says 2.076 feature-wise, bugs that have been fixed 
much later might not be present.
Which is great because it makes bootstrapping *SO MUCH* easier.
