When building dropbear with the following configuration options, a
compilation error occurs. Note that the most important option in
localoptions.h is DROPBEAR_SVR_PUBKEY_AUTH = 0.

localoptions.h:
#define INETD_MODE 0
#define DROPBEAR_X11FWD 0

Build output:
svr-chansession.c: In function ‘sessioncommand’:
svr-chansession.c:682: error: ‘struct ChanSess’ has no member named
‘original_command’
---
This is fixed with the attached patch, which adds a missing #if...#endif.
