Hi Everyone,
I'm on Darwin OS X 10.9 x86_64. I'm trying to upgrade to GnuPG 2.2.15 from https://www.gnupg.org/download/. libgpgerror is giving trouble on Solaris.
```
gmake[2]: Entering directory '/Users/build/libgpg-error-1.35/src'
gawk -f ./mkerrnos.awk ./errnos.in >code-to-errno.h

```
It looks like it is a known problem with [Gawk 5.0](https://github.com/soimort/translate-shell/issues/285). Something about [switching to Gnulib](https://lists.gnu.org/archive/html/info-gnu/2019-04/msg00002.html).
```
$ command -v gawk
/opt/local/bin/gawk
$ /opt/local/bin/gawk --version
GNU Awk 5.0.0, API: 2.0
...
```
