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.
