- support for SCO_SV dynamic loading
- on Mac, auto-detect dynamic loading by __CFM68K__ or _powerc)
- on Mac, long shared library extension is .cfm68k.slb or .ppc.slb
- on hp, don't redefine hpux if already defined
- add __file__ property to successfully loaded module

from marshal_loads()).

to work as hard (but "stringizing" is still used, so we test the newly
introduced HAVE_OLD_CPP config define).

- check for pre-ANSI preprocessor (needed by operator.c)
- SCO_SV shared library support (Lance)
- improved AIX shared library support (Vlad & Manus)
- finally fixed --with-readline=DIRECOTRY, using LDFLAGS

Geoff Philbrick <philbric@delphi.hks.com> (slightly changed by me).

Also a little change to make the file acceptable to K&R C compilers
(HPUX, SunOS 4.x).

Added hacks for GetEventQueue (so you don't have to edit Events.h)

- define USE_CHECKSTACK
- Comment on defines used

- new SpinCursor (replacing Jack's almost-identical one)
- use GetEventQueue in stead of GetEvQHdr

USE_MAC_DYNAMIC_LOADING are no longer needed. Also, WASTE and IMG
removed in some places.

floatobject.c.

Expanded powi() in-line.
