I work around this by undef'ining ENABLE_SFTP manually in config.h. Then 
I get compilation errors:

scponly.c:82: error: `PROG_SFTP_SERVER' undeclared here (not in a function)
scponly.c:82: error: initializer element is not constant
scponly.c:82: error: (near initialization for `dangerous_args[0].name')

Here is a patch:
