Some old platforms (NetBSD, AIX) implement the common stdio "putchar()"
function as a global macro which poisons the global namespace, preventing
all C and C++ programs from using "putchar()" as a function or method.
There was a long thread about this in fltk.coredev during the period
Mar 25 2024 ~ Apr 4 2024, subject "RFC: Fl_Terminal::putchar() in public API"
as to why we have no choice but to not use putchar() as a method name.

-----------------------------
This directory contains tests and demos of FL. In most cases you can
learn a lot about how to program FL by looking at the source code.
Type "make" to compile them all.
The program "demo" is a graphical interface to run all the demos. (you
may recognize this as a rewrite of an XForms program).
Some of the more interesting programs:
fractals: A GLUT program with FL controls added to it
glpuzzle: A GLUT program with no modifications
fullscreen: Demo of how to make your window toggle to fill screen
list_visuals: necessary to debug X visual stuff
mandelbrot: A true application, using panels built in Fluid
menubar: Demo of how FL's menus work
shiny: Demo of drawing FL's controls using OpenGL
forms: An XForms program to demonstrate emulation
colbrowser: Another XForms program that is actually useful
