Configure failing why?

[Samuel M. Smith]

I found a workaround,that is, to disable attribute caching using the  
"noac" nfs option.

#These two worked on tiger 10.4.3
exec -c "console=ttyAM0,115200  
ip=10.0.2.155:10.0.2.150:10.0.2.1:255.255.255.0:ts7250  
nfsroot=10.0.2.150:/Data/nfsroot,noac"

#fstab entry they have to match
10.0.2.150:/Data/nfsroot/ / nfs noac,noauto 0 0

#If use noac,sync,dirsync then gcc does not work
