Apparently automake 1.11 and 1.13  (or rather the Makefiles they
generate) use different conventions regarding the naming of the header
files built by bison/yacc. Automake 1.11 uses *.h for both C and C++
headers, and automake 1.13 names C headers as *.h and C++ ones as
*.hpp. By the way, renaming the sources (*.yy -> *.ypp) seems to have
no effect at all (I guess the change which actually fixed the automake
1.13 build was `#include "ginsh_parser.hpp"').

Hence we need to convince automake 1.13 to produce ginsh_parser.h from
ginsh_parser.{yy,ypp}, or the other way around -- convince the older
versions of automake to produce ginsh_parser.hpp file.

Best regards,
