fltk/configure.in
Michael R Sweet a5778a1864 Updated README and distribution packages to use v1.0.1.
Updated makefiles and makeincludes to use DSONAME and GLDLIBS.

Updated configure.in to use DSONAME instead of LIBNAME.

Updated editor example code in documentation.

Added ANSI C++ changes to make things compile with the latest EGCS
compiler.
