Uh, this is completely cryptic to me, and searching in the internet
doesn't give me a single clue what it really means.

IMHO, this is essentially impossible. FreeType doesn't use
designators (this is, a leading dot before a structure or union
member), only `offsetof'. It rather looks as if the notation for
extended field designators is not defined in the C standard, and the
clang version you use doesn't properly hide its use in its internal
macro definitions so that `-pedantic' gives a warning.
Please contact the clang people and ask for an explanation.
