165  * the data model in which the code that declares the ulong_t is compiled:
166  * four bytes on 32-bit architectures and eight bytes 64-bit architectures.
167  * If the kernel is 64-bit and a 32-bit process executes in a solaris10-
168  * branded zone, then if the process' emulation library, which is 32-bit,
169  * queries the kernel for the zone's emulation bitmap, then the kernel will
170  * refuse because the library will request a bitmap that's half as big
171  * as the bitmap the kernel provides.  The 32-bit emulation library would need
172  * its own macros to define and operate on bitmaps with 64-bit array elements.
173  * Thus using the sys/bitmap.h macros is probably more troublesome than
174  * defining and using our own constants and macros for bitmap manipulations.
