odcctools and pmac g4

hallo all,
i' m andrea from italy and have a problem with odcctools.
wen i try to make on my powermac g4 (dual g4 @450, the "gigabit  
ethernet" model), with tiger 10.4.2 (darwin 8.2.0) and xcode tools  
2.1, i obtain this error:
bytesex.c: In function 'swap_i386_thread_fpstate':
bytesex.c:1316: error: 'struct <anonymous>' has no member named  
'environ'
bytesex.c:1316: error: 'struct <anonymous>' has no member named  
'environ'    (and so on..)
how can correct this?

and another question: can i use odcctools to recompile xnu instead  
cctools provided by apple?

tia
