`squiz_box` is a dlang library for compression and decompression.
I am able to compile this `ldc2` and `dmd`, but not `gdc`. The
error appears to be related to the line `import squiz_box`,
removing of which causes the program to compile successfully, as
the `main` function doesn't call the `squiz_box` library at all.
```bash
dub build --compiler=gdc --verbose

I cannot figure out this error is caused by `squiz_box` libray,
`gdc` or `dub`. My apologies to you if I should have filed this
bug in other places. Thanks for your attention.
