Compile problem on AIX (file locking error)

[WooMeng]

Hi! I'm a new to Samba. I'm trying to complie Samba 2.0.5a to a AIX 4.2
box, but the Configure script complaints about not finding File locking.
The error as follow:
	checking configure summary
	ERROR: No locking available. Running Samba would be unsafe
	configure: error: summary failure. Aborting config

So I went to check for flock, and it's there. I couldn't find any related
docs in Samba sites for how to solve this problem... Does anyone has any
idea? Thanks a lot.
