Geoff,
Isn't the gcc.misc-tests/linkage.c failing just because we don't have
an entry in linkage.exp that defines the native flags for Darwin? Also,
this test look pretty dicey in that it uses...
catch { exec cc -c $native_cflags "$srcdir/$subdir/linkage-y.c"
>&/dev/null }
and...
catch { exec c89 -c $native_cflags "$srcdir/$subdir/linkage-y.c"
>&/dev/null }
which makes me wonder how in the world you can be sure it will be executing the
compiler you just built for testing (instead of whatever is in /usr/bin)?
Jack
