Why?
What made you think that a --target option is required? (clue: it is not
required.)
This works fine for me, with Msys on WinXX hosts...
../configure

OK - so FLTK had built fine and is working (needless target setting aside...)

No, rather I suspect you are missing a setting in your compiler.
You MUST ensure that the value WIN32 is defined in your build. With gcc based
compilers you would add -DWIN32 somewhere in the compiler options.
Or, you can put a suitable define in a header file that is included before any
fltk headers are read.. (e.g. #define WIN32 1 in a project wide header
somewhere.)
If you have the Msys shell, run fltk-config to build your code, it will do the
Right Thing for you...
