<h2><a name="6">Preprocessor macros controlling the library</a></h2>
<p>Some of the semantics of the libstdc++-v3 implementation are
controlled by preprocessor macros, both during build/installation and
during compilation of user code. Many of these choices are made when
the library is built and installed (actually, during
<a href="../configopts.html">the configuration step</a>, with the
various --enable/--disable choices being translated to #define/#undef).
</p>
<p>All library macros begin with <code>_GLIBCPP_</code>. The fact that
these symbols start with a leading underscore should give you a clue
that (by default) they aren't meant to be changed by the user. :-)
</p>
<p>These macros are all gathered in the file <code>c++config.h</code>,
which is generated during installation. <strong>You must assume that
these macros cannot be redefined by your own code</strong>, unless we
document otherwise here. Some of the choices control code which has
already been compiled (i.e., libstdc++.a/.so). If you explicitly
#define or #undef these macros, the <em>headers</em> may see different
code paths, but the <em>libraries</em> which you link against will not.
If you want to experiment with different values, you must change the
config headers before building/installing the library.
</p>
<p>Below are macros which, for 3.1 and later, you may change yourself,
in your own code with #define/#undef or with -D/-U compiler flags.
The default state of the symbol is listed. &quot;Configurable&quot;
(or &quot;Not configurable&quot;) means that the symbol is initially
chosen (or not) based on --enable/--disable options at configure time.
<dl>
<dt><code>_GLIBCPP_DEPRECATED</code></dt>
<dd>Undefined by default. Not configurable. Turning this on enables
older ARM-style iostreams code, and other anachronisms. This may be
useful in updating old C++ programs which no longer meet the
requirements of the language.
</dd>

Can this actually be turned off and still produce a working lib? Must
check. -pme
No, it can't. Hmmm. -pme
<dt><code>_GLIBCPP_RESOLVE_LIB_DEFECTS</code></dt>

corrections and updates from the ISO committee, see

If you have code which depends on the first version of the standard,
you might try undefining this macro.

<h2><a name="3_5">3.5 <code>_XOPEN_SOURCE</code> / <code>_GNU_SOURCE</code>
/ etc is always defined</a></h2>
<p>On Solaris, g++ (but not gcc) always defines the preprocessor
macro <code>_XOPEN_SOURCE</code>. On GNU/Linux, the same happens
with <code>_GNU_SOURCE</code>. (This is not an exhaustive list;
other macros and other platforms are also affected.)
</p>
<p>These macros are typically used in C library headers, guarding new
versions of functions from their older versions. The C++ standard
library includes the C standard library, but it requires the C90
version, which for backwards-compatability reasons is often not the
default for many vendors.
</p>
<p>More to the point, the C++ standard requires behavior which is only
available on certain platforms after certain symbols are defined.
Usually the issue involves I/O-related typedefs. In order to
ensure correctness, the compiler simply predefines those symbols.
</p>
<p>Note that it's not enough to #define them only when the library is
being built (during installation). Since we don't have an 'export'
keyword, much of the library exists as headers, which means that
the symbols must also be defined as your programs are parsed and
compiled.
</p>
<p>To see which symbols are defined, look for CPLUSPLUS_CPP_SPEC in
the gcc config headers for your target (and try changing them to
see what happens when building complicated code). You can also run
<code>&quot;g++ -E -dM - &lt; /dev/null&quot;</code> to display
a list of predefined macros for any particular installation.

New in 3.0.95:
---
- add S390, m68k, x86-64 support.
- doxygen documentation has been extended, including man pages.
- verbose terminate handling has been added.
- some libsupc++ tweaks
- warnings for deprecated headers now active.
- dejagnu testsuite preliminary documentation.
- dejagnu testsuite default.
- dejagnu testsuite cross compiler, multilib safe.
- long long iostreams on by default, rework of ISO C99 support.
- iterator re-write and testsuites.
- container testsuites.
- allocator revamp and testsuites.
- more concept-checking work.
- basic_string optimization and MT fixes.
- new limits implementation.
- update -fno-exceptions code, verify it works.
- full named locale support fpr all facets, choice of gnu,
ieee_1003.1-200x (POSIX 2), or generic models. Full support depends
on target OS and underlying "C" library support.
- more named locale bug fixes
- support for symbol versioning when using GNU ld >= 2.12
- wide-io
