A language may choose which IEEE formats to support.  The C bindings allow 
an implementation to support IEEE 754 for binary, decimal or both.

DFP support in glibc would look rather different from both stand-alone 
libdfp and add-on libdfp (for example, through integrating DFP support 
into <bits/mathcalls.h> rather than having separate headers with DFP 
declarations).
