The most interesting changes this month were probably:

 - 115928 - a common rand() implementation

 - 117265 - failing system calls on embedded NULs

 - 3330 - warning on ++$foo when $foo isn't a number, or magically
   incrementable

 - 85104 - preserving $^E across signal handlers

[perl #115928] This month I implemented perl's new rand()
implementation, avoiding the portability issues of random number
generators on various platforms.  This does not provide a
cryptographically usable rand(), but means that some platforms now
generate a larger selection of random numbers, rather than the say
32768 different possible numbers on Win32.  This wasn't applied until
September.

[perl #117265] I did some clean up of the safesyscalls patch and
finally applied it this month.

[perl #3330] This adds a warning when the user attempts to use perl's
increment operator on a string that isn't a number and doesn't match
/^[A-Za-z]+[0-9]+/.

[perl #85104] I produced an alternative fix for this in July, but
hadn't written any tests until now.  I first attempted to generate
SIGINT and SIGBREAK using kill, hopefully trying to test a "real"
operating system delivered signal, but the signal wasn't being
delivered, even when I went direct to the API using
GenerateConsoleCtrlEvent().  Unfortunately Windows would never deliver
the event without signalling the whole console, possibly killing the
TEST or harness process too.

I ended up using a thread and perl's Win32 signal emulation to test
that $^E is preserved.
