This patch

http://gcc.gnu.org/ml/gcc-cvs/2005-09/msg00882.html

I got

when configuring libjava/classpath. The problem is CXX in libjava alone isn't
suitable to compile C++ executables on Linux/x86_64.

Commenting out AC_PROG_CXX should work.  It was something which was reverted in the import.

------- Additional Comments From mckinlay at redhat dot com  2005-09-26 22:36 -------
AC_PROG_CXX is, presumably, needed by classpath in order to build the Qt peers.
Although this is not the default configuration, it means we can't remove
AC_PROG_CXX.

The libjava configure gets around this issue using GCC_NO_EXECUTABLES, which
disables linking of configure tests where possible. One solution is to add
GCC_NO_EXECUTABLES to the classpath configure.

Unfortunatly this introduces a divergance from the upstream configure.ac. We
also need to butcher classpath's AC_CHECK_FUNCs because many of these do not
work with GCC_NO_EXECUTABLES. However, they are probably not needed anyway
because we do not build classpath's JNI code - only the AWT peers. Perhaps the
AC_CHECK_FUNCs can be made conditional so as to reduce divergance from upstream?

Same problem on s390(x)-ibm-linux.

B.t.w. isn't the real problem that the CXX that comes out of the configure
machinery is simply incorrect?  I.e. it should be something like "xgcc -x c++"
instead of just "xgcc" ...

However, I don't follow the configure machinery enough to understand why this
comes about, sorry.
