portability bug (shell syntax)

I am using libtool-2.2.10 on a
SunOS chase-sun 5.10 Generic_118833-20 sun4u sparc SUNW,Ultra-4

Line 665 of libtool is:

  func_arith_result=$(( $* ))

Apparently this syntax is not portable, as Sun's /bin/sh gives:

../libtool: syntax error at line 665: `func_arith_result=$' unexpected

Should it perhaps be something like this?

  func_arith_result=`expr $*`

Best wishes, -- Peter
