Boost.Compatibilty library

This library provides workarounds which allow the other Boost libraries to be used on otherwise non-conforming platforms. We hope that it will be possible to remove this library at some time in the future as standard library suppliers become more conforming.

Missing C++ standard library CXX headers (e.g <cstdio>) workaround

The Python script: creates a full set of C++ C header files (e.g. <cstdio>) that are missing on some platforms. The header files created by this script reside in the directory boost/compatibility/cpp_c_headers. To use the header files, add this directory to the include file search path. For example:

cxx -I/usr/local/boost/boost/compatibility/cpp_c_headers ...

Supported platforms are:

There are more powerful alternatives to using the Boost.Compatibility library CXX headers, e.g. STLport or ISOCXX. However, in contrast to these alternatives, the script is very light-weight (less than 100 non-comment lines of Python code), much less ambitious, significantly easier to maintain and therefore more suitable as an interim workaround.

Missing C++ standard library <limits> header workaround boost/limits.hpp

Several Boost libraries require the standard library's <limits> header, yet this header is not always supplied by non-conforming compilers and libraries.  Header boost/limits.hpp simply includes the standard library <limits> header if available, otherwise includes boost/detail/limits.hpp.  BOOST_NO_LIMITS from boost/config.hpp is used to determine <limits> availability.

Note also the test program limits_test.cpp
