[Cython] Cython code fails to compile with gcc 2.95

[Stefan Behnel]

Hi,

I know, that's a pretty old compiler, but I know someone with a Solaris
production setup that still uses it. Here is the compile error he gets:

--------------------------------
src/lxml/lxml.etree.c: In function `__pyx_PyInt_AsLongLong':
src/lxml/lxml.etree.c:110165: parse error before `long'
src/lxml/lxml.etree.c:110167: `val' undeclared (first use in this function)
src/lxml/lxml.etree.c:110167: (Each undeclared identifier is reported only once
src/lxml/lxml.etree.c:110167: for each function it appears in.)
src/lxml/lxml.etree.c: In function `__pyx_PyInt_AsUnsignedLongLong':
src/lxml/lxml.etree.c:110185: parse error before `long'
src/lxml/lxml.etree.c:110187: `val' undeclared (first use in this function)
error: command 'gcc' failed with exit status 1
--------------------------------

The problem lies in the new type conversion functions:

--------------------------------
 110156 static INLINE PY_LONG_LONG __pyx_PyInt_AsLongLong(PyObject* x) {
 110157     if (PyInt_CheckExact(x)) {
 110158         return PyInt_AS_LONG(x);
 110159     }
 110160     else if (PyLong_CheckExact(x)) {
 110161         return PyLong_AsLongLong(x);
 110162     }
 110163     else {
 110164         PyObject* tmp = PyNumber_Int(x); if (!tmp) return
(PY_LONG_LONG)-1;
 110165         PY_LONG_LONG val = __pyx_PyInt_AsLongLong(tmp);
 110166         Py_DECREF(tmp);
 110167         return val;
 110168     }
 110169 }
 110170
 110171 static INLINE unsigned PY_LONG_LONG
__pyx_PyInt_AsUnsignedLongLong(PyObject* x) {
 110172     if (PyInt_CheckExact(x)) {
 110173         long val = PyInt_AS_LONG(x);
 110174         if (unlikely(val < 0)) {
 110175             PyErr_SetString(PyExc_TypeError, "Negative assignment to
unsigned type.");
 110176             return (unsigned PY_LONG_LONG)-1;
 110177         }
 110178         return val;
 110179     }
 110180     else if (PyLong_CheckExact(x)) {
 110181         return PyLong_AsUnsignedLongLong(x);
 110182     }
 110183     else {
 110184         PyObject* tmp = PyNumber_Int(x); if (!tmp) return
(PY_LONG_LONG)-1;
 110185         PY_LONG_LONG val = __pyx_PyInt_AsUnsignedLongLong(tmp);
 110186         Py_DECREF(tmp);
 110187         return val;
 110188     }
 110189 }
--------------------------------

So it seems like this line doesn't compile:

--------------------------------
PY_LONG_LONG val = __pyx_PyInt_AsLongLong(tmp);
--------------------------------

Given the error, I would say that "PY_LONG_LONG" gets expanded to the usual
"long long".

Any idea what could go wrong here and what to do about it?
