I noticed the compile warning caused by it and looked for the
reason. I didn't notice any problem but such conflicts are a bug
waiting to happen so I tried to fix it.
The best fix would be to prefix all tokens(say TOK_) so
one doesn't risk conflicts but that was too much work and need
to change the *.m4 files which I don't speak.
