0.5.1, but also ecc05cdd60

Description

I've tried packaging this for pkgsrc. My test system is a NetBSD-10.99.12/x86_64.
The build seems to mostly work fine, but at the end, linking fails with:

   Compiling unrar v0.5.7
error: linking with `cc` failed: exit status: 1

  = note: ld: cannot find -lc++: No such file or directory

My system does not provide a libc++ library, but it has a libstdc++ one. I think that is quite common, so I wonder if there's some code that checks for this and just doesn't trigger correctly on my system.

Current Behavior

Linking fails, see above.

Expected Behavior

Linking succeeds.
