clarification on use of --enable-threads

[Aniruddha Jahagirdar]

Why does the compiler (gcc) have to know in advance what threading model is it be used on the
given machine ? 
How does specification of the threading model affect exception handling ?
Can't I build code that uses threading if --enable-threads is not supported on the platform I am
using (example - alphaev56-dec-osf5.1) ?
