Problem

When building with lastest NGINX mainline version via dpkg-buildpackage, the following error occurs:

ngx_waf version: current branch v10.1.1

Solution

I searched on the web and found this ticket in NGINX's trac, which says:

The issue is caused by modules including system headers prior to nginx ones. In this particular case, it leads to undefined GNU_SOURCE macro and thus missing type declaration.

Then I tried to fix it in my fork and succeeded, so I created a PR. But the code may not be elegant (I know little about NGINX modules' development). You can edit it to prettify the code.
