It wasn't finding nonmember operators with a class of the form:

cdef cppclass C:
  C operator+(const C&, int)

(i.e. with the class specified first)

It's sometimes useful to have nonmember operators in c++
e.g. C operator+(int, const C&)
(So int can come first)

These could be defined outside the "cdef cppclass" section
but if they were in a pxd file they weren't easy to import
and use.

They can now be defined with the "cdef cppclass" and will
be found and used appropriately
e.g.

cdef cppclass C:
  C operator+(int, const C&)

Appropriate tests have been added

	CHANGES.rst

revert integer literal suffixing again and instead generate C hex literals if no suffix is used to make the C compiler consider unsigned types for their values (see C standard 6.4.4)

Allow passing more than two -v's to cygdb.

Constants in float.pxd are not integers.

Additions to includes

- append U-suffix only on coercion when the target type is unsigned
- append L/LL-suffix when value looks too large for a smaller constant value type

- append U-suffix only on coercion when the target type is unsigned
- append L/LL-suffix when value looks too large for a smaller constant value type

undef unwanted defines from longintrepr.h

wrap POSIX dynamic linking API and stdio.h extensions

Fix typo and add missing comma.

fix bytes literal creation from compile-time DEF expressions (used to become Unicode strings due to missing encoding)
