But in any case, ylwrap must also be fixed, if people still
want to stick to it.  And, BTW, glr parsers, C++ parsers
etc. are broken by ylwrap currently as they all use a
header and depend upon it.

A future version of bison will use it too for plain parsers.
People stuck with an old Automake can make a "y.tab.h" file
that just #includes "the-right-header.h" to work around the
