gnupg/common/mischelp.h
Werner Koch 164c687cb6
common: New functions timegm_u64, isotime2epoch_u64.
* common/mischelp.c (timegm): Move to ...
* common/gettime.c (timegm): here.  On Windows use timegm_u32.
(timegm_u32): New.
(isotime2epoch): Factor code out to ...
(isotime_make_tm): new helper.
(isotime2epoch_u64): New.
(_win32_timegm): Remove duplicated code.
(parse_timestamp): Use of timegm.
(scan_isodatestr): Fallback to isotime2epoch_u64.

This mainly helps on 32 bit Windows.  For Unix we assume everyone is
using 64 bit or shall wait until the libc hackers finally provide a
time64_t.

length computation directly with the little twist of adding 1 extra

there are also rumours that 4.3 Reno and DEC systems need it. This
one-off buglet did not harm any current system until it came to Mac
OS X where the kernel (as of May 2009) exhibited a strange bug: The
systems basically froze in the connect call if the passed name
contained an invalid directory part. Ignore the old Unices. */
