Update of bug #17000 (project gnustep):

                 Summary: base/SSL's makefile uses incorrect gnutar usage =>
'gnutar' might actually be 'star'


Follow-up Comment #7:

This is tricky.

So we have this alternative 'tar' program called 'star' 
which has slightly different options than GNU tar, but pretends 
to be GNU tar by installing 'gnutar' as a symlink to itself.

So you may end up with a system where 'tar' is GNU tar,
while 'gnutar' is actually 'star'!  That sounds crazy. :-)

I suppose the only real workaround is to write a configure
test to check that the tar program that we choose supports
the option --exclude-from that we need.  That would definitely

Another option, less safer, would be to check the output
of --version.  Presumably star, even when invoked as 'gnutar',
doesn't cheat to the point of replicating the output
of GNU tar's --version ?
