After installing texinfo and flex, I made a little progress, but
another problem arise.

I updated the code to version c338d4bceb084a629b479e1ac36ab2b42737e1c2
and compiling failed with  a  'simple' error

c-exp.c:1:1: error: return type defaults to ‘int’ [-Werror=return-type]

In build-directory I found a c-exp.c, in which there is only one line

main() { return 0; }

I guess this is a bug.
