This is basically a problem with your FreeBSD installation, not with
eCos. Expecting users and scripts to use tclsh8.4 rather than tclsh,
upgrading each time a new version is installed, is just as silly as
expecting them to use ls-5.2.1 instead of ls because that happens to
be the current version.

What should happen is that tclsh is a symbolic link to tclsh8.4, or
whatever the latest installed version of Tcl happens to be. Older
versions like tclsh8.3 may be installed as well if necessary,
coexisting with the latest. This is in accordance with the Filesystem
Hierarchy Standard, http://www.pathname.com/fhs/
