3.79 not correctly checking archive members

[Devon Miller]

In remake.c, f_mtime() calls ar_member_date() to obtain the mtime on a archive
member.
ar_member_date() returns (time_t)-1 if the member is not found.
The result is then passed to the FILE_TIMESTAMP_FROM_S_AND_NS() macro to create
a FILE_TIMESTAMP.
The resulting FILE_TIMESTAMP is later compared to (FILE_TIMESTAMP)-1 to determin
if an error occurred.

If FILE_TIMESTAMP is of type "unsigned long long"
AND
if ST_MTIME_NSEC is defined

the result of FILE_TIMESTAMP_FROM_S_AND_NS( -1, 0 ) is not equal to
(FILE_TIMESTAMP)-1
and the member is reported as having a bogus future date.

Here's the pacth to fix it:

diff -c make-3.79/remake.c.~1~ make-3.79/remake.c
