I have just updated my svn trunk version, I have installed the recent versions of flex (2.5.35), bison (2.4.1), autoconf (2.64), and boost (1.40).
I then run
trunk$ autoreconf -i -s trunk$ make -C preprocessor trunk$ make -C preprocessor Makefile:15: *** missing separator. Stop.
I am attaching the preprocessor/Makefile that gets generated
Thanks for any help
