tg won't compile on Raspberry Pi

[triss]

tg won't build on Raspberry Pi running the latest Raspbian as per instructions in README.

When running make I get a casting warning/error:

gcc -I. -I. -I./tgl -g -O2  -I/usr/local/include -I/usr/include -I/usr/include -I/usr/include/lua5.2  -DHAVE_CONFIG_H -Wall -Werror -Wextra -Wno-missing-field-initializers -Wno-deprecated-declarations -fno-strict-aliasing -fno-omit-frame-pointer -ggdb -Wno-unused-parameter -fPIC -iquote ./tgl -c -MP -MD -MF dep/queries.d -MQ objs/queries.o -o objs/queries.o tgl/queries.c

How do I build tg on the RPi?
