compiling lsh-1.5.3 with tcpwrappers support

Hi,

after my initial problems with compiling lsh-1.5.3 are solved now, I
thought I'll give tcpwrappers a try. Actually, I want to run lsh thru
Dan Bernsteins tcpserver [1], and my assumption is that enabling
tcpwrappers support for lsh will allow me to do this. If I'm completely
wrong here - how can I do it anyway? :)

After a configure --with-tcpwrappers, make stops here:

make[4]: Entering directory `/usr/local/src/lsh-1.5.3/src'
gcc  -O2 -march=i386 -mcpu=i686 -fPIC -Wall -W   -Wmissing-prototypes

What's the problem here?

System is RedHat 7.1, /usr/lib/libwrap.a belongs to tcp_wrappers-7.6-18.
If you need more details, please let me know.
