[scponly] Enabling SCP

[Brian Koontz]

Using version 4.6 on OS X 10.3.8, I was unable to effect a file
transfer using scp from a remote machine.  After setting the
debuglevel to 2, this was the syslog output: 

scponly[28029]: 3 arguments in total.
scponly[28029]:         arg 0 is scponly
scponly[28029]:         arg 1 is -c
scponly[28029]:         arg 2 is scp -t /Users/scpdemo/project.log
scponly[28029]: opened log at LOG_AUTHPRIV, opts 0x00000029
scponly[28029]: retrieved home directory of "/Users/scpdemo" for user
"scpdemo"
scponly[28029]: setting uid to 503
scponly[28029]: processing request: "scp -t /Users/scpdemo/project.log"

scponly[28029]: denied request: scp -t /Users/scpdemo/project.log
[username: scpdemo(503), IP/port: ww.xx.yy.zz 33306 22]

Further investigation revealed ENABLE_SCP2 was not defined in
config.h, despite the inference in the INSTALL file indicating that
SCP is enabled by default.  I reconfigured using the following:

./configure --enable-scp-compat

Problem solved!
