Thanks for the updated patch. I don't know why I've just received your
e-mail (but it is from Friday).

Today (Sat, around 12:00 CET), I've spent some time on testing your
previous work and write some comments/fixes in the other mail.

The code can be found in:
https://github.com/lmajewski/y2038_glibc/commits/mktime_v3_fixes

The biggest problem from Y2038 support point of view is with removing
__time64_t from posix/bits/types.h
(more explanation in the other mail).


Best regards,
