I think so. As recently as Solaris 8 this approach had trouble since the POSIXish shells were optional and often were not installed. However, starting in Solaris 9 /usr/xpg4/bin/sh has been part of the core packages so we can assume it's there. If someone wants to build on Solaris 8 or earlier we can just ask them to install the optional SUNWxcu4 package, or (if that's too much trouble) to build and install an old Bash version to bootstrap the latest Bash version with. Solaris 8 is still in use (I have one production system at UCLA that still has it, for software-licensing reasons) but it's well past the stage where it's a common build target so it's OK to impose on Solaris 8 some extra hassles like this. It would be helpful to document this assumption in the manual, if we take this step.
