00057  * The platform lacks support for double-width integer division (64-bit
00058  * division on a 32-bit platform, 128-bit division on a 64-bit platform).

00063  *
00064  * The bignum code uses double-width division to speed up some operations.
00065  * Double-width division is often implemented in software that needs to
00066  * be linked with the program. The presence of a double-width integer
00067  * type is usually detected automatically through preprocessor macros,
00068  * but the automatic detection cannot know whether the code needs to
00069  * and can be linked with an implementation of division for that type.
00070  * By default division is assumed to be usable if the type is present.
00071  * Uncomment this option to prevent the use of double-width division.
00072  *
00073  * Note that division for the native integer type is always required.
00074  * Furthermore, a 64-bit type is always required even on a 32-bit
00075  * platform, but it need not support multiplication or division. In some
00076  * cases it is also desirable to disable some double-width operations. For
00077  * example, if double-width division is implemented in software, disabling
00078  * it can reduce code size in some embedded targets.
