-: I looked at the automake installed files and it appears to come from
-: share/automake/am/yacc.am. But in yacc.am, the names are y.tab.<whatever>. I
-: haven't found what does changes '.' to '_' yet.

I don't know if there is a canonical solution to this problem,
but for my own stuff I use a fragment like this in Makefile.cfg:

ifneq ($(COMSPEC),)
        DOT = _
        EXEEXT = .exe
        SEP = ;
else
        DOT = .
        EXEEXT =
        SEP = :
endif

after which I make reference only to y$(DOT)tab.h, foo$(EXEEXT), etc.
