When not configuring with '--host=i386-pc-solaris2.8', it is config.guess that detects 'i386-pc-solaris2.8', just tried here with most recent config.guess on i86pc Solaris2.10, result is 'i386-pc-solaris2.10'. Actually, it is uname showing the 'i386' on Solaris: $ uname -p # Prints the current host's ISA or processor type. i386 $ uname -i # Prints the name of the platform. i86pc So I'd wonder if '--host=i386-pc-solaris2.8' actually does make any difference here. Just my 2 cents. /haubi/
