RE: [Bug-tar] [GNU tar 1.17] testsuite: 12 40 41 42 failed

[EXCOFFIER, Denis \(CS SYSTEMES INFORMATION\)]

Hello,

For #40, it is perfect (now skipped).
For #41 and #42, it still does not work because (if i understand well) the 177 
chars 'this_is_a_very_..._prefix' added to the current working directory 
overtake the 260 PATH_MAX limit.

It may work for some people. Please add an AT_SKIP_TEST condition for that.

Regards.

Denis Excoffier.

Actually, on cygwin, the current limit is PATH_MAX for the corresponding
absolute name of all files (regardless of how short a relative name is),
and is set to 260 due to the limitations of Win9x on FAT file systems
(barely over the POSIX-mandated 256, but rather shy of the XSI minimum
standard of 1024).  A future version of cygwin may be able to expand that
to 32k, which is the NTFS file system limit.

Anyway, here's how I fixed the problem when packaging the cygwin distro of
tar; could we get this patch applied upstream?  With this patch, plus the
fix for test 12, all tests passed or were skipped on cygwin for tar 1.17.
 It relies on gnulib's fcntl.h replacement guaranteeing that O_BINARY is
defined to 0 on platforms where it is not needed.
