# 20230103 bkw: BUILD=3, get rid of useless install instructions.

# 20210910 bkw: fix build on -current (gcc11)
# TODO: occasionally nted segfaults on exit, fix if possible. It's
# difficult to reproduce, and when I compile with debugging symbols
# I can't get it to happen at all.

# 20180905 bkw: upstream has been dead a while, switch homepage to
# debian's package page, and use their patches. VERSION now 1.10.18_12,
# original version + debian patchlevel 12. The debian patches fix a few
# segfaults, and compile issues with later gcc versions (like the one
# in -current, and whatever will end up in 15.0).

# 20170621 bkw: fix build on -current (gcc7's pickier, use -Wno-narrowing)
