pipes + forks?

[lazer1]

with various variants of AmigaOS eg m68k, there arent 
full implementations of pipes and forks,

I was wondering whether glibc could bring fully functioning 
pipes and forks to AmigaOS?

Which Unix API calls does glibc implement?

does it implement fork()??
does it implement pipes fully?

I see files with names like fork.c, but its not clear if 
these are implementations or are just stubs,

How much work would it be to bring glibc to eg m68k-amigaos 
and i686-pc-aros (little endian reimplementation of AmigaOS)?

According to the documentation these 2 OSes arent currently supported,
