Subject: [PATCH] BUG: fix integer size confusion in handling array's ndmin
argument
The ndmin local variable was changed from an "int" to an "npy_intp" but
&ndmin is passed to PyArg_ParseTupleAndKeywords against a "i" argument
spec, but these integers have different sizes (well on an LP64 platform
anyway). This actually works on a little endian system but fails
on a big endian one. Fix this by converting the local back to an int,
and being a little careful before assigning the result of PyLong_AsLong to
it.
Fixes #14767
