1.4.2: shared library is installed with 644 permission

[kloczek]

https://github.com/rhash/RHash/blob/master/librhash/Makefile#L13 And it should be with 755.

What is your OS?

Permissions of shared libraries are discussed at stackexchange: Why are shared libraries executable?

[kloczek]

On any Unix (Linux/Solarix/*BSD) all libraries should be with 755.

I cannot confirm this.

From the second thought, it is a bug.

RHash aims for portability, including Unix support, but HP-UX requires executable bit to be set for the shared library file, otherwise the library code can't be executed. Also Solaris and NetBSD sets executable bit for a shared library files.

The bug is fixed by 9903be0cb94b84188f9b3a42d6b6b8ca5073372e.

Thank you :)

Fix included into RHash v1.4.3.
