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
270 * compilation environment to pre-__DARWIN_UNIX03.
