# 2.12.1 uses CHAR_WIDTH which is reserved and clashes with some glibc versions, but newer versions of fontconfig
# have broken makefiles which needlessly attempt to re-generate headers with gperf.
# Instead, change all uses of CHAR_WIDTH, and disable the rule that forces header re-generation.
# This can be removed once the upstream build is fixed.
