here it is:

Some time ago, the clang developers upgraded this from a warning to an
error, which is fairly sensible for new code, but maybe not so for c89
and older.
I'm not sure if that was a handy choice, but in any case, you can work
around it by adding -Wno-return-type to CFLAGS.
win.c:826:1: warning: type specifier missing, defaults to 'int'
[-Wimplicit-int]
lux_freewins()
^~~~~~~~~~~~
These warnings can all be ignored for K&R code. Or just add
-Wno-implicit-int to shut them up.
