Is this what we want? I notice that in sslconfig.h SSL_USE_OPENSSL is currently
defined as HAVE_OPENSSL_H. Do you want instead to replicate that for NSS? I.e.,

#define SSL_USE_NSS HAVE_NSS_SSL_H

and then define HAVE_NSS_SSL_H in libjingle.gyp?

Pretty sure you want this in a 'conditions' block (line 135)

['OS!="android"', {
  ...
}]

Probably the same with line 46

I don't know exactly what is the purpose of HAVE_OPENSSL_SSL_H if we already
have the SSL_USE_OPENSSL.

I will check with Justin.

Is this needed now? I guess it will be needed when you land the rest of the
patch?

[Ronghua Wu (Left Chromium), 2012/10/11 00:17:18]

This is needed because in the helper.cc, I've added a NSS RNG.
