Comment (by yawning):

 Replying to [comment:4 cypherpunks]:
 > This is similar to the duplicate declaration of
 `SSL_get_selected_srtp_profile` which was fixed in OpenSSL commit
 [https://git.openssl.org/?p=openssl.git;a=commitdiff;h=3609b02305c3678525930ff9bacb566c0122ea2a
 3609b02305c3678525930ff9bacb566c0122ea2a]. `tortls.c` uses a `#pragma`
 dance (which has been replaced by a single preprocessor macro in master)
 to ignore this type of error and it seems `tor-gencert.c` now also needs
 it.

 Just to be extra clear, it's more than tor-gencert that needs to work
 around this, that's just the occurence I happened to paste.
