problem compiling Hostap against the latest libnl... (prototypes don't match)

[Frantisek Rysanek]

Dear everyone,

sorry to gatecrash your peaceful mailing list... apologies for any 
obvious mistakes on my part, it's rather late and I'm getting sleepy 
:-)

I'm trying to compile "hostap" from a current GIT snapshot
http://w1.fi/gitweb/gitweb.cgi?p=hostap.git;a=summary
last change	Fri, 19 Feb 2010 17:14:41 +0000

against the latest libnl, which appears to be two months old by now:
http://git.kernel.org/?p=libs/netlink/libnl.git;a=summary
last change	Wed, 16 Dec 2009 15:20:46 +0000

What I get is this:

I've tried redirecting the include path for netlink headers into the 
libnl build directory, using the relevant three lines in the Makefile 
(obscuring the system-wide headers at the same time), but the result 
is the same.

Any ideas are welcome :-)
