It works for me there:

  $ uname -a
  SunOS gcc-solaris10 5.10 Generic_Virtual sun4u sparc 
SUNW,SPARC-Enterprise
  $ printf 'a\003b\n' | /usr/bin/tr '[:cntrl:]' '[ *]'
  a b $

Solaris 10 /usr/bin/tr has trouble in multibyte locales. Perhaps that's 
your problem? 'configure' should set LC_ALL=C early on, though, so if 
this is your problem it suggests that part of your script is messing 
with the locale, when it shouldn't be.

I installed the attached doc patch into Autoconf master to document more 
of the tr issues.
