All programs get -lc automatically, so this change didn't do anything.

nm on libc.{a,so} on a Solaris 2.5.1 system suggests to me that
Solaris' libc does *not* have a snprintf function, just __snprintf.

snprintf is used in tclcl.  Autoconf should detect its presence or
absence and use our version (in Tcl2.cc) if necessary.  Sadly, this
process seems to have failed for you.

As a work-around, remove HAVE_SNPRINTF from tclcl's makefile and
rebuild.  If you can take a little more effort and let me know why
tclcl's configure failed to detect a missing snprintf, though, that'd
be helpful.

I would guess that there's something odd about your particular build
environemnt since Solaris was one of our test platforms (and autoconf
failed).
