Hello Tatsuro,

this looks like name clash of "CALLBACK" to me. We use this in the enumeration 
in line 9387 of graphics.h and since you are using FLTK 1.3 you include for 
windows the fltk header file "Fl_Native_File_Chooser_Win32.H" where CALLBACK is 
used in another context. It sould be defined in of the windows header files 
e.g. <windows.h>, but I have not looked it up yet.

So, in short term you could try to use fltk 1.1.10, which does not have a 
Native File Chooser. In the long term we need to find another solution, since 
FLTK 1.3 (becoming FLTK 1.4 sometimes) has some nice widget we could use (like 
this native file chooser). We could rename our enumeration to something like 
OCT_CALLBACK, OCT_FOREGROUNDCOLOR or something else ... .
