fltk/src/Fl_File_Icon2.cxx
Michael R Sweet c147aca054 Add flstring.h header file to include string functions, strcasecmp 
definitions, and (v)snprintf function declarations...

Fix Fl_File_Chooser so it always checks for an empty directory_ (so
that is doesn't add the leading slash to drive letters and mount
points)

Make Fl_File_Icon use Fl_Shared_Image, and look in all KDE icon
directories.

Fl::error() no longer exits by default; only Fl::fatal() does...

Wasn't doing callbacks in Fl_Tabs when the current tab was changed
via the keyboard.

FLUID wasn't writing the tooltips in message files, and didn't count
tooltips when computing the message number for catgets.

Update dependencies.
