According to Eric Blake on 4/26/2008 6:35 AM:
| | This is not documented in the autoconf manual, section "Limitations of
| | Usual Tools". But I can confirm the fact:
| |
| | $ { echo moon; echo light; } | /usr/ucb/tr -d '\n' ; echo
| | moo
| | light
| |

I noticed Bruno went one step further in gnulib:

+# Find out how to remove carriage returns from output. Solaris /usr/ucb/tr
+# does not understand '\r'.
+if echo solaris | tr -d '\r' | grep solais > /dev/null; then
+  cr='\015'
+else
+  cr='\r'
+fi
+
~ # normalize output
- -LC_ALL=C tr -d '\r' < t-xstrtoimax.tmp > t-xstrtoimax.xo
+LC_ALL=C tr -d "$cr" < t-xstrtoimax.tmp > t-xstrtoimax.xo

Is this workaround worth documenting, as a way to avoid the ASCII
dependency on \015?
