* 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.
