gcc 3.1 and flex 2.5.4

[Rune Zedeler]

Should the lexer-gcc-3.1.sh be in a working condition in current cvs?
I cannot get it to work.

First time i run it (before configure) i get an error about a missing 
file, and second time it configures correctly but when I make I get a 
bucnh of flex errors.
