by real compiler classes. Also has some utility methods used by
several compiler classes.
The basic idea behind a compiler abstraction class is that each
instance can be used for all the compile/link steps in building a
single project. Thus, attributes common to all of those compile and
link steps -- include directories, macros to define, libraries to link
against, etc. -- are attributes of the compiler instance. To allow for
variability in how individual files are treated, most of those
attributes may be varied on a per-compilation or per-link basis.

to perform the various stages of compilation. The exact set of
executables that may be specified here depends on the compiler
class (via the 'executables' class attribute), but most will have:
compiler the C/C++ compiler
linker_so linker used to create shared objects and libraries
linker_exe linker used to create binary executables
archiver static library creator
On platforms with a command-line (Unix, DOS/Windows), each of these
is a string that will be split into executable name and (optional)
list of arguments. (Splitting the string is done similarly to how
Unix shells operate: words are delimited by spaces, but quotes and
backslashes can override this. See
'distutils.util.split_quoted()'.)

compiler object. The optional parameter 'value' should be a
string; if it is not supplied, then the macro will be defined
without an explicit value and the exact outcome depends on the
compiler used (XXX true? does ANSI say anything about this?)

this compiler object. If the same macro is defined by
'define_macro()' and undefined by 'undefine_macro()' the last call
takes precedence (including multiple redefinitions or
undefinitions). If the macro is redefined/undefined on a
per-compilation basis (ie. in the call to 'compile()'), then that
takes precedence.

list of strings). Overrides any preceding calls to
'add_include_dir()'; subsequence calls to 'add_include_dir()' add
to the list passed to 'set_include_dirs()'. This does not affect
any list of standard include directories that the compiler may
search by default.
N)r )r �dirsr r r! �set_include_dirs� s zCCompiler.set_include_dirsc C s | j �|� dS )a� Add 'libname' to the list of libraries that will be included in
all links driven by this compiler object. Note that 'libname'
should *not* be the name of a file containing a library, but the
name of the library itself: the actual filename will be inferred by
the linker, the compiler, or the compiler class (depending on the
platform).
The linker will be instructed to link against libraries in the
order they were supplied to 'add_library()' and/or
'set_libraries()'. It is perfectly valid to duplicate library
names; the linker will be instructed to link against libraries as
many times as they are mentioned.
