Configure script wrongly probe things and then FTBFS:

termcap.c:45:14: error: conflicting types for 'boolcodes'; have 'char *[]'

      |              ^~~~~~~~~

Note that simply fixing up termcap.c will cover up the real issue and produce an zsh executable hanging at runtime. The upstream changes can be done via sed:

sed -i -e 's/^main/int &/' -e 's/exit(/return(/' aczsh.m4 configure.ac
sed -i 's/test = /&(char**)/'                    configure.ac
autoreconf
