<pre>
    A number of GNU extensions to the Fortran standard library are used in practice by various packages.

So far when building a corpus of opensource Fortran code I've noticed the lack of:
* `etime` (example user: [LAPACK](https://netlib.org/lapack/) )
* `rshift` (example user: [AVL](http://web.mit.edu/drela/Public/web/avl) )
* `secnds` (example user: [AVL](http://web.mit.edu/drela/Public/web/avl) )
* `getpid`(example user: [AIRSS](https://airss-docs.github.io/) )
* `hostnm` (example user: [AIRSS](https://airss-docs.github.io/) )
