Bug 1077: Recommend support for wide-character regcomp and regexec and/or specify multi-byte behavior OPEN
http://austingroupbugs.net/bug_view_page.php?bug_id=1077

Andrew has completed the action to ping his Apple contact and is
awaiting a reply.

Bug 1106: *rand48(): Should this use uint16_t instead of unsigned short? Rejected
http://austingroupbugs.net/view.php?id=1106        

The standard permits uint16_t and unsigned short to be distinct
types, even if they have the same bitwise layout; on such an
implementation, changing the signature would cause a compilation
error on existing code due to type mismatch. These interfaces are
intended for backwards compatibility, not for use in new code.
Since changing the signature could break existing code, we have
decided to reject this change request.

Bug 0001107: *rand48(): We don't explain how the LCG state is 'transformed into the returned value'  Accepted as Marked
http://austingroupbugs.net/view.php?id=1107

This item is tagged for TC3-2008

Replace this sentence on P749, L25537-25539:
    Then the appropriate number of bits, according to the type of
    data item to be returned, are copied from the high-order
    (leftmost) bits of X<sub>i</sub> and transformed into the
    returned value.

with:

    X<sub>i</sub> is then converted to the return value as follows:

    - For drand48() and erand48() the value shall be 2<sup>-48</sup> times X<sub>i</sub>.
    - For jrand48() and mrand48() the value shall be the largest integer not greater than 2<sup>-16</sup> times X<sub>i</sub>.
    - For lrand48() and nrand48() the value shall be the largest integer not greater than 2<sup>-17</sup> times X<sub>i</sub>.


Change the EXAMPLES section on P750, L25571 from:
    None.
to:
    The following program tests that the required pseudo-random
    number generator is used by these functions.


and then add the contents of the file rand48-test-vectors.c attached
to this bug, but with main() changed to main(void).


Bug 1108: LONG_MIN must be <= -2147483648 OPEN
