I guess not, it looks that the system *tried* to execute ac++.

To run the ac++ executable, the system needs to get
version information from the shared object (because ac++ was linked to a
specific version of the shared library). In this case the libstdc++.so.5
seems to not provide version information. To confirm that you can run:

$ objdump -p libstdc++.so.5 | grep SONAME

If you get nothing, the your installed libstdc++ doesn't provide version
information, which is needed to run executables linked to specific
versions of shared libraries.

Yes, the static ac++ executable should work.
