dnl ===========================================================================
-dnl Generally, it is a bad idea to put specialized header files for a library
-dnl into a generic directory like /usr/local/include/. Instead, one should put
-dnl them into a subdirectory. GiNaC does it, NTL does it. Unfortunately, CLN
-dnl doesn't do so but some people choose to do it by hand. In these cases we
-dnl need to #include <cln/cln.h>, otherwise #include <cln.h>. This macro
-dnl tries to be clever and find out the correct way by defining the variable
-dnl HAVE_CLN_CLN_H in config.h:
-AC_DEFUN(GINAC_CHECK_CLN_H,
- [AC_PROVIDE([$0])
- AC_CHECK_HEADERS(cln/cln.h, ,
- AC_CHECK_HEADERS(cln.h, ,
- AC_MSG_ERROR([cannot find header for Bruno Haible's CLN]);

+dnl Usage: GINAC_RLVERSION
+dnl The maintainers of libreadline are complete morons: they don't care a shit
+dnl about compatiblilty (which is not so bad by itself) and at the same time
+dnl they don't export the version to the preprocessor so we could kluge around
+dnl incomatiblities. The only reliable way to figure out the version is by
+dnl checking the extern variable rl_library_version at runtime. &#@$%*!
