--- Comment #3 from Iain Sandoe <iains at gcc dot gnu.org> ---
gcc version 12.0.1 20220429 (prerelease) [gcc-12-1rc1 revision
r12-8321-g621650f64fb6] (GCC)=20
gcc-12-1-darwin mini-07-cat:gcc-git-12 isandoe$
/opt/iains/x86_64-apple-darwin19/gcc-12-1rc1/bin/gcc
gcc: fatal error: no input files
compilation terminated.

$ /opt/iains/x86_64-apple-darwin19/gcc-12-1rc1/bin/g++
ld: -rpath can only be used when targeting Mac OS X 10.5 or later
collect2: error: ld returned 1 exit status

So, we have some addition to the command line from the g++ driver that is
causing this (the actual reported problem is not significant, the reason is
that the command line is not being seen as empty by the darwin driver)=
