Outch, sorry. My mistake. I had seen that exceptions.h might be needed
if !HAVE_PYTHON, but was lazy and only did a visual check.  I should
have attempted a build --without-python.

Unfortunately, this is not the right fix.  2 things:
  - The needed include was conditionalized on HAVE_PYTHON, so the
    right fix was simply to move the #include out of the conditionalized
    section;
  - the right include is "exceptions.h", not "../exceptions.h".
    Sources in python/ are compiled from the gdb/ subdirectory.

I have applied the following patch to fix the problem.

        Fix build failure when building without Python support.
        * python/python.c: Always include exceptions.h, even when HAVE_PYTHON
        is not defined.

Tested by rebuilding GDB --with-python and --without-python.
