We are only talking about /usr/ucb/tr on Solaris 10:
$ echo solaris | /usr/xpg4/bin/tr -d '\r'
solaris
$ echo solaris | /usr/xpg6/bin/tr -d '\r'
solaris
$ echo solaris | /usr/bin/tr -d '\r'
solaris
$ echo solaris | /usr/5bin/tr -d '\r'
solaris
$ echo solaris | /usr/ucb/tr -d '\r'
solais
Since we are already stating in the generic INSTALL file, since 2008:
On Solaris, don't put '/usr/ucb' early in your 'PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in '/usr/bin'. So, if you need '/usr/ucb'
in your 'PATH', put it _after_ '/usr/bin'.
your precautions above are coping with a situation that is unsupported
anyway.
In GNU gettext, many tests use "tr -d '\r'" since 2007 already, and no one
ever has reported a problem with it.
