shortcut which assumes the list is empty for large requests
too.

arenas if allocation failed.
Patch mostly by Jan Edler <jan.edler@indexengines.com>.
waste bins[0..1].

(_int_malloc): Fix test for large enough buffer for early termination.
When no unsorted block matches perfectly and an exiting block has
to be split, use full list insert and not shortcut which assumes
the list is empty.
platforms define as 1MB. For 64-bit platforms as 32MB. The lower
limit is needed to avoid the exploding of the address space
requirement for secondary heaps.

there is causing more trouble than it's worth.

rather than the alignment of double.
(union fooround): Use uintmax_t, long double, void * members
rather than just long and double.
[BZ #321]
Fix portability bugs encountered when porting to the IBM iSeries,
where pointers are 256 bits wide and no integers are that wide.
