if it integrated more naturally with bison, these might seem like
better arguments :) i could *perhaps* live without flex's input file, 
but making do without a bison grammar file as the basis for a parser
seems like a sure way towards madness. but then again, i've never
tried to use gscanner and bison, so perhaps its easier than it looks.
i also don't recall how much support for regexps gscanner has. i
should go and look.
