Yes, and this is why scripts like 'configure' automatically reexecute 
themselves with bash or ksh or whatever, if they find themselves running 
on Solaris 10 /bin/sh. Although it's a bit awkward, it's better than 
trying to live within the intersection of the old SunOS sh and a POSIX 
shell. In 'sed' you found one script that wasn't doing that, but Jim has 
fixed that now (by removing the script!).

I just now checked and ./configure still tries sh5, an Ultrix-based 
POSIXish shell that was last released in 1995! We have the late Fred 
Canter to thank for that, I imagine. See:
