GOB 1 on cygwin: flex and lex

[Pieter Engelen <engelen pieter gmail com>]

Hi, 
I'm trying to port Gtk+ Object Builder 1.0.9 to cygwin. the configure
runs whit whout any problems. except for

checking whether to enable maintainer-specific portions of Makefiles... no
what is this??

when I do make 
I get :

bison -y -d -t  parse.y
parse.y:976.35-42: integer out of range: `$<cbuf'
parse.y:977.39-46: integer out of range: `$<cbuf'
make: *** [parse.h] Error 1

What am I doing wrong?

Is this because cygwin uses flex and no lex?
