mac/macsetfiletype.c: changes by Jack to execute .pyc file passed
as command line argument. On the Mac .pyc files are given a
special type so they can be double-clicked
*module.o/*module.so
* Python/import.c: if initializing a module did not enter the
module into sys.modules, it may have raised an exception -- don't
override this exception.
Merged NT changes
* Python/import.c: add lost NT-specific code back in
Fixed NT changes
In Pythonrun, tirn off SIGPIPE and move signal handlers elsewhere.
In ceval.c, also move locals_2_fast/ fast_2_locals to frameobject.c,
replaced local variable trace by f->f_trace, got rid of unused
mergelocals() and unneeded calls to fast_2_locals, return the variable
name on "fast variable not found", AND use "__call__" method if it
exists to call an inmstance. Whew!
compile.c: lists and dictionary in code objects become tuples
import.c: bump MAGIC
thread*.[ch]: added thread_ident() function
version.c: added '++' to version number and bumped date
