The compiler construction toolkit of GMD Karlsruhe, Germany, has all
the features that you want. Its scanner generator, REX, does line
buffering and keeps track of the source position in a struct with
members line and column. There is also a converter from LEX input to
REX input included.


It has been announced in this group before, and can be ftp'd from
/rusmv1.rus.uni-stuttgart.de:/soft/unix/programming/compilerbau/...
