From the perspective of automake, it gets even worse, if you consider 
what bison (and maybe flex) do to filenames on DOS. There's some hideous 
mangling of the filenames to fit into the 8+3 short filename convention, 
if only short filenames are available (Windows '95 and later support 
long filenames).

   foo.y -> foo.tab.c (Linux, Unices & DOS with LFNs)
   foo.y -> foo_tab.c (DOS with SFNs)

The nasty part of this is that bison does this mangling without being 
told to. The only sane solution I came up with was to always tell it the 
file prefixes of the output files. But that breaks automake-generated 
Makefiles, IIRC.

Bye, Rich =]
