* description:
*
* This is a Posix-compatible version of <stdlib.h> for both Posix
* and non-Posix systems.
*
* Notes:
* o The presence of a prototype here does not guarantee the existence
* of the corresponding function in the library.
*
* o `div_t' and `ldiv_t' are not declared since their declarations
* cause conflict on antique compilers with a single struct namespace;
* hence div() and ldiv() are not declared either.
*
* o Some implementations have conflicting (or just plain wrong)
* return types of qsort and/or srand. These can be accommodated
* by setting the macros _P_QSORT_RETURN_TYPE/_P_SRAND_RETURN_TYPE.
