Re: libtool 2.2.6 does not install libraries correctly on HP-UX

Hi Ralf,

See below. Yes it does have chmod 555.

I think so, yes. Once you have coreutils, sed, and whatever installed and
they all depend on libintl, you are immediately hosed if the replacement
of the shared library is not done atomically.

The "chmod 555" afterwards is not wrong. But it would be good if you could
also apply a heuristic: Look for the arguments of the --mode=install command.
If you find consecutive arguments '-m' and '644', replace the second one
with '755'.
