point taken, patryk told me the same thing. however, it remains that there
is a nasty interaction between multiple targets and parallel makes.

yes, it's nasty. i grab all the tokens from lexer.l, generate an enum in
the .h for them, and a token-to-string function in the .c. put it down to
a phobia about #including files containing code (and also putting code in
headers).
