FC3 and ispell

[Pashka]

Hi All,
I have problems installing ispell-3.2.06
When I run make, the following erros appears in the console window :
+ cc -O -c term.c
term.c: In function `terminit':
term.c:310: error: `TIOCGETP' undeclared (first use in this function)
term.c:310: error: (Each undeclared identifier is reported only once
