doc: avoid problems with case insensitive file systems
makeinfo --html generates index.html, and the node "Index" will result
in Index.html. On case insensitive file systems, such as on Mac OS X
by default, this results in a single, invalid, file (Texinfo 4.13).

since, of course YYSTYPE_IS_TRIVIAL is defined. Instead we could

later is defined, but let's avoid stacking CPP on top of M4: rather, use

The testsuite in master has shown weird errors for the "Mulitple
Parsers" tests: the caller of p5.parse() received some apparently
random value, while tracing p5.parse() showed that the function was
consistently returning 0.
It happens when mixing several parser headers, some generated without
%debug, others with. In particular the C++ parser was generated with
%debug, i.e., with:
#ifndef YYDEBUG
# define YYDEBUG 1
#endif
and compiled separatedly. Yet, its header was included after the one
of another parser, this time without %debug, i.e., with
#ifndef YYDEBUG
# define YYDEBUG 0
#endif
in its header. As a result, the parser was compiled with YYDEBUG set,
but its header was used without. Since the layout of the objects are
then completely different, boom.
Therefore, do not change the value of YYDEBUG. Rather, use it as a
default value for <API.PREFIX>DEBUG.
