Re: Announcing FreeType 2.10.3

[Chris Liddell]

So, we've had a report that building Ghostscript against Freetype 2.10.3
fails because FT_CALLBACK_DEF() has been moved to internal use only.

Ghostcript supplies callbacks for memory management (i.e. FT_MemoryRec)
and we used FT_CALLBACK_DEF() for those, which seemed logical when
defining callbacks!

Is there now an alternative way to do that? Or should we just switch to
explicitly declaring them static?

Cheers,

Chris
