The problem here is that strtold does not work correctly on ppc-darwin because the ABI changed for long double and the size. This is just one of the problems darwin 7.0's headers and libraries. the fortran failure for large_real_kind_1.f90 is the same issue except there is no header at all because fortran does not use the C headers. The fortran failure is also on darwin8 too. I will be filing a radar (Apple's bug database) for this issue too. Though I really doubt they will fix this issue.
Radar 4225347.
I am going to mark this as depending on PR 25477 for now. I am almost ready to submit the patch for PR 25477 again.
No longer working on this, too much troubles are causing to me to fix Darwin bugs.
Tracking this as part of the general problem under 25477. *** This bug has been marked as a duplicate of 25477 ***
