Hello,
I am trying to use mir-cpuid library, written by il9

Within the library

     pragma(crt_constructor)

is used.

I can see that these two new pragmas were incorporated by this 
merge
https://github.com/dlang/dmd/pull/7182
(and the author of mir-cpuid library commented how useful this 
is, in the discussion thread)

The DMD change log from about 1.5 years ago, announces those 2 
new pragams
https://dlang.org/blog/2018/01/04/dmd-2-078-0-has-been-released/


I am trying to use
gdc-9 (Ubuntu 9.1.0-2ubuntu2~18.04) 9.1.0

And my sample code including this library fails at compilation 
stage, saying that crt_constructor pragma is not known.


I am D newbie, therefore i might not appreciate all nuances.

But with these compilation error,  does it mean that I am running 
into
a situation where  given D (or in this case Better-C ) library
might be compatible with one compiler (eg DMD), but not with 
another (GDC) ?


Or is there a switch/workaround that can deployed for DUB that 
addresses those things during external package assembly stage 
(things that go into my ~/.dub) folder ?

Another question, is there way to know by looking at given 
librarie's description or dub.json what compiler it is compatible 
with?

Thank you in advance
