           Summary: BigInt declaration is not recognized
    Classification: Unclassified
           Product: GDC
           Version: 4.8.x
          Platform: x86_64

The following compiles fine under (Linux 64) dmd 2.063.2:

import std.bigint;

BigInt a = "9588669891916142";

int main(string[] args) {

    return 0;
}

but it fails under (Linux 64) gdc (Ubuntu 4.8.1-5ubuntu1) 4.8.1:

/usr/include/d/4.8/std/internal/math/biguintcore.d:1511: Error: reinterpreting
