+compiling siproxd for FLI4L
+===========================
+
+2.0.x (libc5 based):
+
+   1) LIBOSIP
+   On an libc5 system (eg SUSE 5.3), first build and install
+   libosip. Probably you get an error when building in file
+   parser/port_misc.c, telling you about a non existing include
+   file sys/unistd.h. To fix this, simply edit the .c file and
+   replace the erroneous include statement to include <unistd.h>
+   instead of <sys/unistd.h>
+   $ ./configure
+   $ make 
+   $ make install
+   
+   2) SIPROXD
+   Delete the config.cache file.
+   Configure siproxd:
+   $ ./configure --enable-almost-static
+   This will build siproxd statically linked against libosib, 
+   pthreads and dynamically against libc. Then
+   $ make
+   
+
+
+
+
+2.1.x (uClibc based):
+   Prerequisite: uClibc development enviroment installed
+
+
+   1) LIBOSIP
+   Does not build very smoothly and properly. However, to link siproxd
+   STATICALLY against libosip this procedure might work.
+   Apply same fix to port_misc as described above.
+   Apply the following path to configure.in

+     --with-extra-libs=<libosip_install_prefix>/lib --enable-almost-static
