This is rather irritating.

This is rather irritating.

We override exit() throughout the httpd build in order to intercept and
report our status through the service control manager.

We must include process.h prior to overriding exit().

I seem to remember that this is the reason apr.hw once included
process.h unilaterally, to avoid this conflict over exit.
