# IIgs: large overflow segments. --segment-cap bounds the ENTRY bank (which
# also holds rodata + bss + heap); overflow banks carry text only, so capping
# them the same way wasted ~50K per bank. With this AGI links 5 bank-aligned
# segments instead of 19, which matters because it already needs -ramsize 4M.
# Verified by running KQ3 headless and diffing AGI's own joeylog.txt against
# the 19-segment build: identical apart from the embedded build timestamp.
# See JoeyLib's make/support/iigs/clang-build.sh for the measurements.
