Sorry for not having this in the body, in the cover message I added to
Claire's email with:

The problem is with certain build system, we use bazel at Google,
where iquote is used for includes within the library, and other
flavors outside the library. There's a similar conversation here:
https://groups.google.com/g/bazel-discuss/c/6MNuZ5bKoa8?pli=1

the failure you see when building is:

In file included from src/event-parse.c:27:
src/event-utils.h:13:10: error: 'event-parse.h' file not found with
<angled> include; use "quotes" instead
#include <event-parse.h>
         ^~~~~~~~~~~~~~~
         "event-parse.h"

Arguably -iquote is more correct within the library build, hence bazel
using it. The libtraceevent Makefile is using -I, hence this not being
a problem for others. We prefer not to carry internal patches, hence
wanting to send this upstream.

Thanks,
Ian
