* COMPILATION ENVIRONMENTS -- see compat(5) for additional detail
*
* DEFAULT By default newly complied code will get POSIX APIs plus
* Apple API extensions in scope.
*
* Most users will use this compilation environment to avoid
* behavioral differences between 32 and 64 bit code.
*
* LEGACY Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
* API extensions in scope.
*
* This is generally equivalent to the Tiger release compilation
* environment, except that it cannot be applied to 64 bit code;
* its use is discouraged.
*
* We expect this environment to be deprecated in the future.
*
* STRICT Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
* available APIs to exactly the set of APIs defined by the
* corresponding standard, based on the value defined.
*
* A correct, portable definition for _POSIX_C_SOURCE is 200112L.
* A correct, portable definition for _XOPEN_SOURCE is 600L.
*
* Apple API extensions are not visible in this environment,
* which can cause Apple specific code to fail to compile,
* or behave incorrectly if prototypes are not in scope or
* warnings about missing prototypes are not enabled or ignored.
*
* In any compilation environment, for correct symbol resolution to occur,
* function prototypes must be in scope. It is recommended that all Apple
* tools users add either the "-Wall" or "-Wimplicit-function-declaration"
* compiler flags to their projects to be warned when a function is being
* used without a prototype in scope.
