Bug in configure, section mount.h

Hi,

I'm trying to install Gnunet on an OpenBSD 3.9 sparc64.

The first thing to say is that it's not a plaisure for now : I've tried 
a lot of things for getting the ./configure script to work :

First, the configure script didn't find the GnuPM library (located by 
default in /usr/local on openbsd). I had to define 2 env variables with 
the commands :

export CPPFLAGS="-I/usr/local/include"
export LDFLAGS="-L/usr/local/lib"

the scrip could then continue...

A warning occured during the execution of the script, here is the output :

checking sys/mount.h usability... no
checking sys/mount.h presence... yes
configure: WARNING: sys/mount.h: present but cannot be compiled
configure: WARNING: sys/mount.h:     check for missing prerequisite headers?
configure: WARNING: sys/mount.h: see the Autoconf documentation
configure: WARNING: sys/mount.h:     section "Present But Cannot Be 
Compiled"
configure: WARNING: sys/mount.h: proceeding with the preprocessor's result
configure: WARNING: sys/mount.h: in the future, the compiler will take 
precedence
configure: WARNING:     ## --------------------------------- ##
configure: WARNING:     ## Report this to [email protected] ##
configure: WARNING:     ## --------------------------------- ##
checking for sys/mount.h... yes

And then, the script execution reach the end.

When I try to build the binaries, I get the following :

I've not taken the time for now to look at the source to try to find why 
this error occur. If someone has an idea, I take.

My plateform is somewhat original, so I will try to test it well, if it 
works, I will write a howto to help others.

Thanks in advance for your advices.
