when building on a WIN32 host. I am not sure why these were here, but on one of my (very) non-standard configurations this was causing the build to fail. After some discussion on fltk.dev, we decided to removed them since no one thinks they are needed (please tell me if it turns out that the are!) Note: that discussion also considered whether the other (re)defines in that file, e.g. for stricmp and strnicmp and others were useful; I have left these in place for now, though I beleieve they are not needed nor useful. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@10259 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
