Keith, Okay, let's say that's the solution. Unfortunately, lines 2064-2065 in my configure file are: 2064: ac_link_default=`echo "$ac_link" | sed 's/ -o *conftest[^ ]*//'` 2065: if { (eval echo "$as_me:$LINENO: \"$ac_link_default\"") >&5 I'm willing to modify 2065 by changing 2064, but I don't know where in line 2064 the spurious ":/usr/lib" comes from (nor why it appears, although that is another question).

What is `:/usr/lib', and how has it gotten in there? All I see for this test, with autoconf-2.59 is: configure:1599: checking for C compiler default output file name configure:1602: gcc conftest.c >&5 configure:1605: $? = 0 which clearly passes; it's that spurious `:/usr/lib' that's making it fail for you.
