// like (GCC 2.96) . Do not even think of getting this to work,
// a miserable failure will be guaranteed!
//
// Equally, this file has been tested for RTPs (Real Time Processes)
// only, not for DKMs (Downloadable Kernel Modules). These two types
// of executables differ largely in the available functionality of
// the C-library, STL, and so on. A DKM uses a C89 library with no
// wide character support and no guarantee of ANSI C. The same Dinkum
// VxWorks supports C++ linkage in the kernel with
// DKMs (Downloadable Kernel Modules). But, until recently
// the kernel used a C89 library with no
// wide character support and no guarantee of ANSI C.
// Regardless of the C library the same Dinkum
// STL library is used in both contexts.
//
// Similarly the Dinkum abridged STL that supports the loosely specified
// embedded C++ standard has not been tested and is unlikely to work
// on anything but the simplest library.

// Additional Configuration

//
// Because of the ordering of include files and other issues the following
// additional definitions worked better outside this file.
//
// When building the log library add the following to the b2 invocation
// define=BOOST_LOG_WITHOUT_IPC
// and
// -DBOOST_LOG_WITHOUT_DEFAULT_FACTORIES
// to your compile options.
//
// When building the test library add
// -DBOOST_TEST_LIMITED_SIGNAL_DETAILS
// to your compile options
//
// When building containers library add
// -DHAVE_MORECORE=0
// to your c compile options so dlmalloc heap library is compiled
// without brk() calls
