218 * COMPILATION ENVIRONMENTS
219 *
220 * DEFAULTBy 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 *behavioral differences between 32 and 64 bit code.
225 *
226 * LEGACYDefining _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 * STRICTDefining _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 either 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.

263 * while new code can use a standards compliant version of the same function.
264 *
265 * __DARWIN_ALIAS is used by itself if the function signature has not
266 * changed, it is used along with a #ifdef check for __DARWIN_UNIX03
267 * if the signature has changed. Because the __LP64__ environment
