[antlr-interest] Problem with autotools while using antlr3 C runtime

[金杰]

Hi All,

the antlr3 C runtime is build with autotools.
the autotools generate a header antlr3config.h, this header has
defined: #define PACKAGE "libantlr3c"

my project is also build with autotools, there is a header config.h, which
define: #define PACKAGE "polaris"
when I compile my code, there is an error:

In file included from /opt/antlr3c/include/antlr3defs.h:246,
                 from /opt/antlr3c/include/antlr3.h:33,
                 from PolarisAdmin.cc:13:
/opt/antlr3c/include/antlr3config.h:96:1: error: "PACKAGE" redefined

the error indicate that  "PACKAGE" has redefined.

is it a bug?  (:
how can I avoid this error?

thank you in advance.
