prevents the use of libsafe. Also, the code size savings are negligable (96 bytes for FLUID) Added I18N docos to FLUID chapter. We probably need to expand discussion a lot more in the 2.0 docos. The EPM list installed the static FLTK library with execute permission, which caused EPM to strip the library, making it impossible to link against... :( git-svn-id: file:///fltk/svn/fltk/branches/branch-1.0@1097 ea41ed52-d2ee-0310-a9c1-e6b18d33e121
