OK, I upgraded this box to 8-current; now the bootstrap.sh
'hangs' when compiling gconv_simple.c (I can provide
whole command line ) :
top(1) shows :

OK, I'll hook up a serconsole tomorrow ..
for now some good old quick n dirty copy paste by pen and paper :

sched_switch
mi_switch
sleepq_switch
sleepq_wait
_sleep
linux_vfork
ia32_syscall
Xint0x80_syscall
syscall (190, Linux ELF32, linux_vfork)
11291 (cc1)
sched_switch
mi_switch
sleepq_switch
sleepq_catch_signals
sleepq_wait_sig
_sleep
pipe_write
dofilewrite
kern_writev
write
ia32_syscall
Xint80_syscall
syscall (4, Linux ELF32, write)
Thanx for your help.

bon, in fact when I launce the command by hand adding a '-v ' to gcc, output
says :
/usr/libexec/gcc/i486-pc-linux-gnu/4.1.2/cc1 ... | /usr/lib/gcc/i486-pc-linux-gnu/4.1.2/../../../../i486-pc-linux-gnu/bin/as -V -Qy -o /var/tmp/portage/sys-libs/glibc-2.6.1/work/build-default-i486-pc-linux-gnu-nptl/iconv/gconv_simple.o -
but, cc1 is stuck in 'pipewr' and no .../bin/as process is running (any longer)
nor the file .../gconv_simple.o created

I investigated this a bit more (still chrooted to /usr/local/gentoo-stage3) :
i486-pc-linux-gnu-gcc gconv_open.c -c : OK
i486-pc-linux-gnu-gcc gconv_open.c -c -pipe : OK
i486-pc-linux-gnu-gcc gconv_simple.c -c : OK
i486-pc-linux-gnu-gcc gconv_simple.c -c -pipe : pipe to as(1) fails
I tried to play with kern.ipc.maxpipekva (I vaguely remember that
was necessary for linux testsuites) pumping it up to "536608768", but
no difference. If someone has another suggestion?
Thanx, Arno
