* Added fcmp() to test_support.py and use it in test*.py

data.
Pass an extra parameter to the compression library.

(extensive) comments in the file for usage.

stdwinmodule.c: wsetfont can now return an error
Makefile: add CL_USE and CL_LIB*S; config.c: move CL part around
New things in imgfile; also in Makefile.
longobject.c: fix comparison of negative long ints...  [REAL BUG!]
marshal.c: add dumps() and loads() to read/write strings
timemodule.c: make sure there's always a floatsleep()
posixmodule.c: rationalize struct returned by times()
Makefile: add test target, disable imgfile by default
thread.c: Improved coexistance with dl module (sjoerd)
stdwinmodule.c: Change include stdwin.h if macintosh
rotormodule.c: added missing last argument to RTR_?_region calls
confic.c: merged with configmac.c, added 1993 to copyright message
fileobject.c: int compared to NULL in writestring(); change fopenRF ifdef
timemodule.c: simplify times() using mkvalue; include myselect.h
  earlier (for sequent).
posixmodule: for sequent, include unistd.h instead of explicit
  extern definitions and don't define rename()
Makefile: change misleading/wrong MD5 comments

* mainloop.py: don't use select unless absolutely necessary (for Mac)

Improved coexistance with dl module.

* ceval.c: use #ifdef COMPAT_HACKS instead of #if 0
* Makefile: fix to make clmodule.c compile;
  make config.o dependent on libpython.a (so date is always correct)
* timemodule.c: now sleep() also takes a float argument.
* posixmodule.c: added nice().

* Makefile: svmodule.c.proto and svgen.py are gone, svmodule.c came in
	their stead.  Also, pass -DUSE_DL flag to thread.c and give
	the user a possibility to add the -DDEBUG to just thread.c.
* ceval.c: init_save_thread() can be called more than once now.
* svgen.py, svmodule.c.proto, svmodule.c: Removed prototype file and
	replaced it by the generated file.
* thread.c: Added some more checks; added call to DL library when it
	is also used to tell it where the shared arena is so that DL
	can use some other area.
* threadmodule.c: Call init_save_thread from another place.  Also,
	added new function getlocklock() which does to lock objects
	what getfilefile does to file objects.

* Fixed calendar.py, mimetools.py, whrandom.py to cope with time.time()
  returning a floating point number.  (And fix old bug in calendar)
* Add recursion level to mainloop.mainloop(), to make it reentrant.

* posixmodule.c: move extern function declarations to top
* listobject.c: cmp() arguments must be void* if __STDC__
* Makefile, allobjects.h, panelmodule.c, modsupport.c: get rid of
  strdup() -- it is a portability risk
* Makefile: enclosed ranlib command in parentheses for Sequent Make
  which aborts if the command is not found even if '-' is present
* timemodule.c: time() returns a floating point number, in microsecond
  precision if BSD_TIME is defined.
