fltk/FL/Fl_Browser_.H
Michael R Sweet 4b561b6e90 Updated copyright notices for all of the 1.0.x files.
Updated the configure script for *BSD and GCC 2.95 (-fno-exceptions)

Added install rule to documentation directory.

Dumped old packages directory; added traditional RPM spec file and EPM
list file (that replace all of the packages stuff)

The FLUID man page is now "fluid.1" for the formatted page and "fluid.man"
for the non-formatted page, since only IRIX uses pack'd formatted man pages.

Whew!
