When compiling in default (standard) mode, the compiler has access to the complete library specified by the C++ standard. The library components include what is informally known as the Standard Template Library (STL), as well as the following components.
the standard version of stream I/O classes
basic memory allocation
run-time type information
The term STL does not have a formal definition, but is usually understood to include containers, iterators, and algorithms. The following subset of the standard library headers can be thought of as comprising the STL.
The C++ standard library (libCstd) is based on the RogueWave Standard C++ Library, Version 2. This library is available only for the default mode (-compat=5) of the compiler and is not supported with use of the -compat[=4] option.
The C++ compiler also supports STLport’s Standard Library implementation version 4.5.3. libCstd is still the default library, but STLport’s product is available as an alternative. See 12.3 STLport for more information.
If you need to use your own version of the C++ standard library instead of one of the versions that is supplied with the compiler, you can do so by specifying the -library=no%Cstd option. Replacing the standard library that is distributed with the compiler is risky, and good results are not guaranteed. For more information, see 11.7 Replacing the C++ Standard Library.
