They're working fine for me (I'm using ocamlopt rather than ocamlc though).
The ocaml part of the testsuite works fine for me too but I have an
older gcc (4.1.2), maybe that's why.

This error is in some temporary C file output by ocamlc. The only way
to fix that is probably to modify ocamlc.

I suggest using gcc rather than g++ for this: replace '-cc $(CXX)' by
'-cclib -lstdc++' in the site.exp target of test/Makefile
