Bingo! But I just changed in "configure"...

checking for bison... no
checking for yacc... yacc
configure: warning: You will need bison/yacc as required for various GRASS
modules.

However, how to tell configure.in about it?

It seems to be an autoconf bug (see configure):

  for ac_prog in 'bison -y' byacc

should be

  for ac_prog in 'bison -y' byacc yacc

How can we fix this?
