if builtin STL is used,
settings are saved also for non-interactive installs,
with correct COMPILER string,
compiler are also read from INSTALL_CONF_DIR.

added -frtti flag for all g++'s in any case :)
changed CONFIG_PREFIX to CGAL_CFG instead of CGAL_CFG_NO
check for GMP syslib/cgal-inst only the first time GMP_SUPPORT is toggled on
(until now it checked right away after compiler was chosen)
* added support for GMP installation
* more command-line flags for non-interactive mode
* testing is now more transparent and configurable
* custom compiler and linker flags can be defined
* changed command line option '-os' to return the os/compiler setting without any additional output, so this can be used for setting an environment variable which triggers makefile inclusion (asked for by Lutz).
* corrected the order of libs in the various ldflags.
* -frtti for gnu is now only set in rtti-support settings.
* some minor fixes.
* non interactive setting hopefully works now.
* check_LEDA_LIB_DIR accepts also, if there only is a libL.so.
* Added --help reference when something went wrong.
* changed include makefile generation due to Wieger.
* changed cgal_test replacement due to Wieger.
* fixed /bin/wc option "-m" to "-c" which seems to be more portable.
* changed appearance --> fewer stars :)
* logging successful compile runs into a vis_logfile that is displayed when exiting from the script.
* added a remark about the install logfile.
* fixed version number parsing (now only the number is stored in CGAL_INSTALL_VERSION).
* removing old logfiles now works.
* not checking for ${CGAL_DIR}/include anymore, instead check existence of $CGAL_DIR, $CGAL_LIB_DIR, $CGAL_INCL_DIR , $CGAL_MAKE_DIR and that we have read and execute permission for these (write to LIB and MAKE).
* changed g++ version number parsing to work with snapshots.
* added a print_center_line for pretty-printing.
* fixed #error directives in compiler testprogs to @error, since sunpro does not treat them as errors (bug/feature?).
* fixed leda-testprog to end with return 0.
* added a print_os_setting to give the configuration in a readable fashion.
* added test-suite option.
