Right: I always avoid installing before testing to make extra certain to test the freshly built bits and nothing else. > Now I have a concern that we have instances of -Bpath/to/libsomething/.libs > that are present to allow for specs substitution and we also need them for > providing run paths at test time.

Still there is going to be an impact, even on non-Darwin. However, this duplication of -B and -L options is present all over the testsuite already, just nobody cared to do something about it so far. Those Xcode 15 ld warnings my change this, though... > So I think that gcc/lib/gfortran.exp needs to have the library -B/-L additions > structured so that only one set gets added.
