[Bug c++/40871] New: g++ does not find lstdc++ on AIX

[efernandez at physiomics-plc dot com]

On AIX 5.3, g++ version 4.4.0 and 4.4.1 cannot find the libstdc++ in default
location. This did not occur with 4.3.x.
The problem has been already discussed on the mailing list in this thread:
http://gcc.gnu.org/ml/gcc-help/2009-06/msg00092.html
and a patch was issued. It was supposedly committed to the main branch after
4.4.0, but for some reason was not present (or did not solve the issue) in
4.4.1.

I have compiled gcc with --disable-shared and use the AIX linker ld, not the
GNU linker.

This is the verbose compilation output of a simple Hello World program written
in C++:
