Compile Error on Dropbear 2018.76 without PUBKEY

[Stefan Hegny (hydrografix Consulting GmbH)]

Hello,
 
trying to build dropbear-2018.76 for ARM, and trying to
 
#define DROPBEAR_SVR_PUBKEY_AUTH 0
 
in Order to get around CVE-2018-15599, aware that it would not conform to 
IETF, I receive:
 
svr-chansession.c:682:11: error: 'struct ChanSess' has no member named 
'original_command'
 
Is there an #if missing around that line?
 
Thx & regards
Stefan
