Sigh, of course it is.  Fixed.

I was running on Solaris 11.1, which uses ksh93 as its /bin/sh.  You're
absolutely right that Solaris 10 would fall over, though.

Similarly, the following line:

    demangled=$(demangle $sym)

doesn't work on traditional sh.  I've replaced $() with ``.

I updated the first line from the #! invocation to a comment saying

    # This script is invoked via "sh .../gen-version-script.sh".

Would a respun version of these patches help toward testing?
