The compiler is built under Windows using Visual Studio and works very
well, however how can I provide an internationalization?

You can install cygwin and try to download directly bison 2.4 package,
if available.
I think only 2.3 is available at present day;
anyway I have installed cygwin with devel package and I have
successfully compiled (./configure) and installed (make and make
install) bison 2.4.

In this way you can also redefine YYLTYPE (user custom locations), YYLLOC_DEFAULT (to merge locations) and YY_LOCATION_PRINT (to print locations) without any trouble.

I think you can use pointers to C++ class inside a union without any
trouble. Just try it.
Checking what the compiler accepts is a good way to produce
non

example to add a field to the struct to track also file location),
YYLLOC_DEFAULT (to merge locations) and YY_LOCATION_PRINT (to print
locations) without any trouble.
You have to redefine those macro BEFORE to include y.tab.h otherwise
the compiler will complain.

Hi,
I would like to grab a first Bison knowledge by developing the sample

The gnuwin32 setup version I am currently using is
ognize the error and perform the right action
(so they can propagate the error up to the root of the syntax tree).
I suggest to read the follwing pdf:
