Agreed.

Anyway, it looks you got this problem under control ;)

Sorry for the late answer, but my G5 was buzzy regtesting. With the patch in
comment 5, tested with

make -k check-gfortran RUNTESTFLAGS="vect.exp=pr32380.f
--target_board=unix'{-m32,-m64}'"

I get


        === gfortran tests ==
Schedule of variations:
    unix/-m32
    unix/-m64

Running target unix/-m32

/opt/gcc/darwin_buildw/gcc/testsuite/gfortran/../../gfortran  version 4.9.0

So the patch is OK for powerpc-apple-darwin9.
