[ 558914 ] Build md5.c fails on Cray T3E

I've also deleted a comment that I didn't understand.  Feel free to
put it back if it makes/made sense to you.

Using Unicode-aware methods may still die with a NameError on unicode.
Maybe there's a more elegant solution but I doubt anybody cares.)

literals must not contain \u, \U or \N escapes.  (XXX Should they also
not contain non-ASCII characters?)

in there, and convert it to "rb" (or "r" for non-universal-newline builds)
before passing it to fopen().

Fixes #561326.

(or how do I "mark" something to be a candidate?)

fixed an old buglet that caused bdb to be unable to
continue in the botframe, after a breakpoint was set.
the key idea is not to set botframe to the bottom level frame,
but its f_back, which actually might be None.
Additional changes: migrated old exception trick to use
sys._getframe(), which exists both in 2.1 and 2.2 .

Note: I believe Mark Hammond needs to look over his code now.
F5 correctly starts up in the debugger, but later on doesn't stop at a given
breakpoint any longer.

kind regards - chris

[ 559250 ] more POSIX signal stuff

whose tp_mro hasn't been initialized, it would dump core.  Fix this by
checking for NULL and calling PyType_Ready().  Will fix this in 2.2.1

Other minor rewrites

Remove 1.5.2 reference: who cares?

The old syntax suggested that a trailing comma was OK inside backticks,

Minor style changes to make the use of "my" with arrays more consistent.

A MemoryError is now raised when the list cannot be created.
There is a test, but as the comment says, it really only
works for 32 bit systems.  I don't know how to improve
the test for other systems (ie, 64 bit or systems
where the data size != addressable size,
e.g. 64 bit data, but 48 bit addressable memory)
