annotate Python/hypot.c @ 17503:327efb59dbcd legacy-trunk
I am TENTATIVELY checking in Martin von Loewis's patch for the SSL
problem reported by Neil Schemenauer on python-dev on 4/12/01, wth
subject "Problem with SSL and socketmodule on Debian Potato?".
It's tentative because Moshe objected, but Martin rebutted, and Moshe
seems unavailable for comments.
(Note that with OpenSSL 0.9.6a, I get a lot of compilation warnings
for socketmodule.c -- I'm assuming I can safely ignore these until 2.1
is released.)
