To the best of my knowledge, flex has no "last token" function in its
API. It can do *character* context, but not token context. Thus to
properly handle this situation with lex, you'd have to hack it in
manually with inserted C code (most likely by passing info back from the
parser).
I just checked the Ada95 lex spec available from the AdaIC site
(http://www.adaic.org/standards/95lrm_rat/lexer9x.l
). It indeed contains no context information in the token definitions,
and thus should have the same problem. The relevent entries are:
-------------------------------------------
"'" return(TIC);
"'"."'" return(char_lit);
-------------------------------------------
