 Compiling the doc/examples/dataset_example*.cpp with Oracle Solaris Studio
 on intel-S2, we see the following failure:
 $"CC" -compat=5 -library=stlport4 -xO4 -mt -erroff=%none -m32 -KPIC

 "../boost/test/data/monomorphic/fwd.hpp", line 83: Error: "," expected

 ...

 Reason for failure:
  The code of this test is perfectly fine from language standpoint, and the
 failure is related to long-existing bug in all later Solaris versions.
 Basically, compilation of any C or C++ code will fail on Solaris if it
 will satisfy two conditions:

     1) The presence of #include <sys/regset.h> system header, direct or
 indirectly attached through other system headers from /usr/include
 directory.

     2) The presence of identifiers which accidentally coincide with X86
 register names, like CS, DS, ES, ...

 The failure occurs because that /usr/include/sys/regset.h has the
 following macros:

 #define CS 15

 #define DS 3

 #define ES 2

 and when compiler preprocesses this header, after that it automatically
 replaces user identifiers which accidentally have the same names with
 those numbers shown above.

 Possible solution:
 Replace replace DS identifier in
 libs/test/include/boost/test/data/monomorphic/fwd.hpp and
 libs/test/include/boost/test/data/test_case.hpp
 with D_S.
