I'm trying to compile a file that weighs 3 kilobytes. I'm also
linking a self-written dynamic library. I don't understand why
the resulting executable file is so huge? After all, all
libraries are present:
```sh
-rwxr-xr-x 1 root root 6.3M May 27 13:39 app
-rw-r--r-- 1 root root 2.9K May 27 12:57 app.d
-rw-r--r-- 1 root root 25K May 27 13:39 app.o
```
```sh
ldc2 -O app.d -L-lpq -L-lX11 -L-lXrandr -L-lm -L-lmira
```
```sh
