Re: clang on macOS and overzealous warnings

[Greg Troxel <gdt%lexort.com@localhost>]

The plot thickens.  From the bup list, pointed out that

   $AC_CC -Wall -Werror $cflags -c -o "$tmpdir/test" "$tmpdir/test.c"

is a compile-only invocation, with no linking.  However I note that -o
is present to put test.o into a strange (but not prohibited) location
test instead of test.o.

Do people think the wrappers only add LDFLAGS to link invocations, and
is the -o (vs not having -c) causing a false detect?
