The warning about the fldcr instruction results from a bug in the
assembler (which is fixed in DG/UX 5.4R2.01).  However, the warnings
may be ignored; they do not affect the correctness of the object file.
They result from the fact that recent versions of gcc use the fldcr
instruction to synchronize volatile memory references.
