modification history
--------------------
02r,12nov13,cww  Added getenv_s() (WIND00430431)
02q,11oct11,mcm  Cleanup (WIND00288946)
02p,01jul10,jpb  Removed alias for taskExit.
02o,29apr10,pad  Moved extern C statement after include statements.
02n,13sep04,yvp  Made taskExit an alias for exit().
02m,26mar01,max  Fixing a type
02l,26mar01,max  According to the AltiVec ABI, we need to introduce new
                 functions for memory allocation/deallocation:
                 vec_malloc, vec_calloc, vec_realloc, and vec_free.
		 They should be 16-byte aligned and are supposed to be used
		 for memory operations with AltiVec vector data.
02k,10oct00,sn   deleted size_t, wchar_t definitions
02j,17feb99,mrs  Add C++ support for NULL, (SPR #25079).
02i,15oct93,cd   added #ifndef _ASMLANGUAGE.
02h,05feb93,smb  corrected prototype for strtoul
02g,22sep92,rrr  added support for c++
02f,21sep92,smb  reordered prototype list.
02e,24jul92,smb  replaced types.
02d,24jul92,smb  added prototypes for div_r and ldiv_r
		 removed the ifndef for types div_t, ldiv_t and wchar_T
02c,20jul92,smb  replaced modification history.
02b,19jul92,smb  rewritten
02a,04jul92,jcf  cleaned up.
01f,26may92,rrr  the tree shuffle
01e,25nov91,llk  added ansi definitions EXIT_FAILURE, EXIT_SUCCESS, RAND_MAX,
                   MB_CUR_MAX.
                 included more function prototypes.  Some are commented out.
01d,04oct91,rrr  passed through the ansification filter
                  -fixed #else and #endif
                  -changed copyright notice
01c,10jun91.del  added pragma for gnu960 alignment.
01b,19oct90,shl  fixed typo in modhist 01a.
01a,05oct90,dnw  created
