The two ifdefs you added should be either

  #if !defined(USE_OPENSSL)

or

  #if defined(USE_NSS) || defined(OS_MACOSX) || defined(OS_WIN)

The former is more concise.

USE_NSS is only relevent to Linux (including Chrome OS)
and Android. This is why defined(OS_MACOSX) and defined(OS_WIN)
are necessary if you check defined(USE_NSS). I understand
this is complicated. Sorry about that.

I wonder if what you want is SSL_USE_OPENSSL and SSL_USE_NSS (in libjingle's
sslconfig.h). We could then arrange for these to be set properly by the platform

Done.
