Hi again,

i have no definitive answer, only some ideas. I had problems on IRIX
compiling programs that use lex/flex and yacc/bison. I can't remember
how i solved this, but i had the impression that the order in which
libraries (-ll or -lfl) are given on the command line to gcc/linker
matters. You also could check if the makefile calls lex or flex -l
(compatibility mode of flex). Do the two linux machines have different
versions of flex installed? Have no time to dig deeper into lexical
analysing with flex.
