# 20180627 bkw: fix compile with gcc 8 (for -current).

# 20160730 bkw:
# - Fix compile with gcc 5 (for Slack 14.2). Also fix some
#   compiler warnings while I'm at it.
# - Remove warnings about multiplayer not working on 64-bit, it
#   works now.

# Install game data in /usr/share/games/Maelstrom, not /usr/games/Maelstrom
# (also make `make install' support DESTDIR properly!)
patch -p1 < $CWD/install_dirs.diff

# 20180627 bkw: It seems structs and typedefs now share a namespace
# in gcc-8.1's g++. So rename this struct to keep the compiler happy
# on -current (and it does no harm on 14.2 either):
