That line is in process.c since 2013, so what changed lately on your
system that suddenly this is a problem?  Did you update your system
libraries or headers?

Isn't HarfBuzz not yet supported on macOS?  Why do you have HarfBuzz
related flags in your compilation?

Perhaps look in config.log for how HAVE_GLIB got defined, if you don't
have it.

Yes, glib got updated today when I ran 'brew upgrade' today. But that
was a minor upgrade from 2.62.2 to 2.62.3. Here is the log,

When I was trying to configure with HarfBuzz support last week, I
created environment variable. I was trying various ways to include
HarfBuzz. I wasn't aware that HarfBuzz support is not yet implemented on
MacOS. But even with this setting earlier commits worked just fine.

HAVE_GLIB is defined.

Let me just do a "make bootstrap" and report in a while.

I had this a wee while back and, iirc, make bootstrap fixed it.

(Or I may have just rerun autogen.sh and configure, but make bootstrap
does that anyway.)

"make bootstrap" fixed it. Please close this.

Done.
