Hi,
	I just build cln-1.1.13, ginac-1.3.6 myself (OS X 10.4, dual G4)
without problems, and bison didn't even play a role because ginac ships
the resulting .cc sources with it (pre-built using bison 1.875, it seems).
The only reason I can imagine why your build tried to run bison is if the
timestamps were somehow not preserved upon unpacking, or you accidentally
touched the yacc source.  In the case of a timestamp problem can you try
"touch ginsh/*.{h,cc}" to avoid re-running bison?

For comparison, my gcc:

Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /private/var/tmp/gcc/gcc-5363.obj~28/src/configure
--disable-checking -enable-werror --prefix=/usr --mandir=/share/man

gcc version 4.0.1 (Apple Computer, Inc. build 5363)

	Just for kicks, I 'touched' the yacc file to force a rebuild using
our version of bison, 2.3, and it still rebuilt fine for me.  Can you give
some more context on the failure?  For example, what did your configure
report about 'readline', since the line numbers referenced in your report
are all related to readline configuration and the resulting preprocessor
macros.  (I'm using readline-5.0).  You can find some _RL_ results in
"config.h" too.  Just a stab in the dark, does the problem go away if you
wrap those conditionals in one more pair of enclosing parentheses?

	Speaking of fink, anyone on this list consider submitting a
package for cln/ginac?  They are much easier to build than they were a few
years ago, thanks to various libtool and configury updates.
