None of those messages makes terribly much sense.  There is no "array[-1]
of char" declaration of yytext in scanner.h.  And since when did Sun's lex
start to have its yytext a pointer instead of the traditional array?

The complaint in line 519 of scanner.l indicates that you have two tools,
both made by Sun, disagreeing over what a usable expansion of the standard
lex macro yyless() should look like.  There's nothing anyone but Sun could
do about that.

To further clarify this (and also why nobody else reported this particular
type of problem on Solaris), it would be nice if you named horse and rider:
what Solaris, what platform, what cc and what lex?

Summing it up: I recommend you forget about Sun's "lex" and use flex
instead.  Just as the first recommendation in the "Tips" section of the
INSTALL says.
