+
+/* The i386 floating point hardware (the 387 compatible FPU, not the modern
+   SSE/SSE2 hardware) has a controllable rounding precision.  It is specified
+   through the 'PC' bits in the FPU control word ('fctrl' register).  (See
+   the GNU libc i386 <fpu_control.h> header for details.)
+
+   On some platforms, such as Linux or Solaris, the default precision setting
+   is set to "extended precision".  This means that 'long double' instructions
+   operate correctly, but 'double' computations often produce slightly
+   different results as on strictly IEEE 754 conforming systems.
+
+   On some platforms, such as NetBSD, the default precision is set to
+   "double precision".  This means that 'long double' instructions will operate
+   only as 'double', i.e. lead wrong results.
+
+   The FPU control word is under control of the application, i.e. it is
+   not required to be set either way by the ABI.  (In fact, the i386 ABI
+   http://refspecs.freestandards.org/elf/abi386-4.pdf page 3-12 = page 38
+   is not clear about it.  But in any case, gcc treats the control word
+   like a "preserved" register: it emits code that assumes that the control
+   word is preserved across calls, and it restores the control word at the
+   end of functions that modify it.)
+
+   See Vincent Lefèvre's page http://www.vinc17.org/research/extended.en.html
+   for a good explanation.
+   See http://www.uwsg.iu.edu/hypermail/linux/kernel/0103.0/0453.html for
+   some argumentation which setting should be the default.  */
