Enable (or disable) support for the C decimal floating point extension
that is in the IEEE 754R extension to the IEEE754 floating point
standard. This is enabled by default only on PowerPC, i386, and
x86_64 GNU/Linux systems. Other systems may also support it, but
require the user to specifically enable it. You can optionally
control which decimal floating point format is used (either @samp{bid}
or @samp{dpd}). The @samp{bid} (binary integer decimal) format is
default on i386 and x86_64 systems, and the @samp{dpd} (densely packed
decimal) format is default on PowerPC systems.
