it said no for me last time i have tried. maybe it is
because i use FLTK 1.1.9? or maybe, do you have some
headers in windows that i dont have? does windows XP pro
come with any headers anyway? thats probably a stupid
question, but since my win installation is just standard i
wouldnt assume to have it any header files. OTOH, if i had
no headers, how would i be able to build FLTK ^^). maybe
solely because of mingw...?
i will try that configure again, harder! :>
