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.
