           Summary: forward reference bug.
           Product: D
           Version: 2.023
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: someanon@yahoo.com

But according to the specs the compiler is indeed buggy.
The specs say:
| The order in which ImportDeclarations occur has no significance.

//main.d --------------8<---------------
import vec3, mat3, quat;
int main() { return 0; }

// mat3.d--------------8<---------------
module mat3;
import vec3, quat;
struct Mat3 { Vec3[3] m; }

// quat.d--------------8<---------------
module quat;
import vec3, mat3;
struct Quat {}

// vec3.d--------------8<---------------
module vec3;
import mat3, quat;
struct Vec3 { }


I get this back from the compiler....

unixbox$ dmd main.d vec3.d mat3.d quat.d
vec3.d(6): struct vec3.Vec3 no size yet for forward reference
vec3.d(6): struct vec3.Vec3 no size yet for forward reference
vec3.d(6): struct vec3.Vec3 no size yet for forward reference
unixbox$

To everybody reading this: Please look through issues you've reported and check for missing keywords. Moreover, what was the point of the attachment when you've already posted the code? What's more, it's so small that by gzipping it you've actually made it bigger than the original files! Anyway, this seems to be closely related to issue 2386.... --
