RE: Irix6 long doubles implemented wrong? (27_io/ostream_inserter_arith)

I'd prefer that it was correct, even if this means breaking the gcc ABI.

Excellent!  Let me know if I can be of service testing your patch.

Considering the current irix libc incompatibility, one cannot
currently input or output long doubles using stdio.  What good is
