Using `ast2` generates `importc` calls for any constants defined in headers which fails when using `dylib="dynlibFile"`
For example, the following does not work:

```
// libraryname.h
const libraryname_time libraryname_time_zero = 0.0; 
```

if one decides to use the following to import the header file:

```
cImport(srcDir/"libraryname.h", dynlib = "dynlibFile", flags="-f:ast2 --noHeader")
```

It fails at runtime with the message:

```
could not import: libraryname_time_zero
```
