when it returns NULL to indicate failure, it will also free the memory
that was passed to it, if that was non-null.
This does not change the semantics of realloc.
A second commit will be done to commit the conversion of those places in
the code that can safely use this to avoid memory leaks when confronted
with low memory situations.

instead of long long and unsigned long long. Really they should be
quad_t and u_quad_t, but that would require sys/types.h and this
header only includes machine/types.h. The difference here is that
int64_t and u_int64_t on alpha are long and unsigned long, not
long long etc. This is required to pass gcc's type checking where
long != long long even though they are the same size of alpha.
implement (better) falback code inside srandomdev() itself.
Change return type from int to void (binary compatibility surprisely
achieved). Userland code will be changed soon.
for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.
If _ANSI_SOURCE or _POSIX_SOURCE is defined, then <ctype.h> had to
be included before <stddef.h> or <stdlib.h> to get rune_t declared.
Now rune_t is declared perfectly bogusly in all cases when <ctype.h>
is included.
This change breaks similar (but more convoluted) convolutions in the
stddef.h in gcc distributions. Ports of gcc should avoid using the
gcc headers.
Previously they were only guarded by `#ifndef _ANSI_SOURCE'. They are
neither ANSI nor POSIX nor std and should never have been declared here.
Declare functions like abs() as having attribute `__pure2'. Declaring them
as having type `__pure' has been a no-op for some time.
Delete obsolete comment about stub locale functions.
Use consistent formatting for the rand48 functions. These and about 30
other functions should never have been declared here either.
