This is the case after the change in commit XXX of YYYY-MM-DD, ``compile: use 'compile' script when "-c -o" is used with losing compilers''
This is just a simplification; no semantic changes are intended. * automake.in (handle_languages): Drop transform '%-o%', and definitions of '$output_flag'. * lib/am/depend2.am: Adjust to just assume the '?-o?' transform is true, and the '%-o%' transform expands to "-o".
