Compiling Lyx-1.0.2

[Marco Augustin]

Hello Lyx-Team!

I've got a problem with compiling Lyx-1.0.2! I use gcc2.8.0 on a PowerPC Amiga.
When g++ arrives  the spellchecker.C file gcc makes the error: FDSET undefined
refernce and FD_ZERO undefined reference.
I tried also ./configure --with-gcc-hack and the CXXFLAGS options as described
in the problems sections of install document.

What does this error mean? And how can I successfully compile Lyx? 

P.S. With egcs1.1b g++ makes the same mistake!

Thanks for your help
