218	* COMPILATION ENVIRONMENTS
219	*
220	* DEFAULT By default newly complied code will get POSIX APIs plus
221	* Apple API extensions in scope.
222	*
223	* Most users will use this compilation environment to avoid
224	* behavioural differences between 32 and 64 bit code.
225	*
226	* LEGACY Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
227	* API extensions in scope.
228	*
229	* This is generally equivalent to the Tiger release compilation
230	* environment, except that it cannot be applied to 64 bit code;
231	* its use is discouraged.
232	*
233	* We expect this environment to be deprecated in the future.
234	*
235	* STRICT Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
236	* available APIs to exactly the set of APIs defined by the
237	* corresponding standard, based on the value defined.
238	*
239	* A correct, portable definition for _POSIX_C_SOURCE is 200112L.
240	* A correct, portable definition for _XOPEN_SOURCE is 600L.
241	*
242	* Apple API extensions are not visible in this environment,
243	* which can cause Apple specific code to fail to compile,
244	* or behave incorrectly if prototypes are not in scope or
245	* warnings about missing prototypes are not enabled or ignored.
246	*
247	* In any compilation environment, for correct symbol resolution to occur,
248	* function prototypes must be in scope. It is recommended that all Apple
249	* tools users add etiher the "-Wall" or "-Wimplicit-function-declaration"
250	* compiler flags to their projects to be warned when a function is being
251	* used without a prototype in scope.
252	*/
253
254	/*
255	* The __DARWIN_ALIAS macros are used to do symbol renaming; they allow
256	* legacy code to use the old symbol, thus maintiang binary compatability
257	* while new code can use a standards compliant version of the same function.
258	*
259	* __DARWIN_ALIAS is used by itself if the function signature has not
260	* changed, it is used along with a #ifdef check for __DARWIN_UNIX03
261	* if the signature has changed. Because the __LP64__ enviroment
262	* only supports UNIX03 sementics it causes __DARWIN_UNIX03 to be
263	* defined, but causes __DARWIN_ALIAS to do no symbol mangling.
264	*
265	* As a special case, when XCode is used to target a specific version of the
266	* OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
267	* will be defined by the compiler, with the digits representing major version
268	* time 100 + minor version times 10 (e.g. 10.5 := 1050). If we are targetting
269	* pre-10.5, and it is the default compilation environment, revert the
