# gcc 7.2 refuses greenlet 3.x's C++ designated initializers wherever they skip
# a field. The rule was probed, not assumed: in-order contiguous is fine, a
# TRAILING gap is fine, an interior or leading gap is refused.
# fill-designators.py writes the skipped fields back as explicit zeros, taking
# field order from the TARGET's own headers and refusing to guess about a
# designator that is not in them. These are objects of static storage duration,
# so every field it inserts was already zero: it changes the spelling, not the
# program. 55 fields across two files.
