a pointer and lack a prototype will have the return value (assumed
to be an integer) zero-extended to a pointer. On ia64 this is
unconditionally fatal as it zeroes-out the region bits, forming an
invalid pointer. Fix the sigsegv by including <stdlib.h>.

Fixed related style bugs:
basename.c: misplaced '#if 0'
dirname.c: misplaced '#if 0'
getgrent.c: missing '#if 0', and tab lossage in vendor id (the previous
commit fixed the complete corruption of the vendor id but
lost a tab)
getpwent.c: missing '#if 0'
