[NB: this is the default, and is the same as<br/> --enable-cheaders=c_global]<br/> <br/> include/c_std<br/> Headers intended to include standard C headers<br/> already in namespace std, and put select names into the std::<br/> namespace. [NB: this is the same as --enable-cheaders=c_std]<br/> <br/> include/bits<br/> Files included by standard headers and by other files in<br/> the bits directory.<br/> <br/> include/backward<br/> Headers provided for backward compatibility, such as <iostream.h>.<br/> They are not used in this library.<br/> <br/> include/ext<br/> Headers that define extensions to the standard library. No<br/> standard header refers to any of them.<br/> <br/> scripts<br/> Scripts that are used during the configure, build, make, or test<br/> process.<br/> <br/> src<br/> Files that are used in constructing the library, but are not<br/> installed.<br/> <br/> testsuites/[backward, demangle, ext, performance, thread, 17_* to 30_*]<br/> Test programs are here, and may be used to begin to exercise the<br/> library. Support for "make check" and "make check-install" is<br/> complete, and runs through all the subdirectories here when this<br/> command is issued from the build directory. Please note that<br/> "make check" requires DejaGNU 1.4 or later to be installed. Please<br/> note that "make check-script" calls the script mkcheck, which<br/> requires bash, and which may need the paths to bash adjusted to<br/> work properly, as /bin/bash is assumed.<br/> <br/> Other subdirectories contain variant versions of certain files<br/> that are meant to be copied or linked by the configure script.<br/> Currently these are:<br/> <br/> config/abi<br/> config/cpu<br/> config/io<br/> config/locale<br/> config/os<br/> <br/> In addition, a subdirectory holds the convenience library libsupc++.<br/> <br/> libsupc++<br/> Contains the runtime library for C++, including exception<br/> handling and memory allocation and deallocation, RTTI, terminate<br/> handlers, etc.<br/> <br/> Note that glibc also has a bits/ subdirectory. We will either<br/> need to be careful not to collide with names in its bits/<br/> directory; or rename bits to (e.g.) cppbits/.<br/> <br/> In files throughout the system, lines marked with an "XXX" indicate<br/> a bug or incompletely-implemented feature. Lines marked "XXX MT"<br/> indicate a place that may require attention for multi-thread safety.<br/> </p></div></div><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td align="left"><a accesskey="p" href="appendix_contributing.html">Prev</a> </td><td align="center"><a accesskey="u" href="appendix_contributing.html">Up</a></td><td align="right"> <a accesskey="n" href="source_code_style.html">Next</a></td></tr><tr><td align="left" valign="top">Appendix A.
