Albrecht Schlosser a5d2d19a23 Fix usage of 'volatile' in src/Fl_JPEG_Image.cxx (#1207)
- allocate a new struct 'load_stat' on the heap
- use struct load_stat to open image file (fp) and for error counters

The previous fix of #1207 unfortunately decremented volatile variables
which caused (plausible) compiler warnings by clang.

README - Fast Light Tool Kit (FLTK) Version 1.4.3

WHAT IS FLTK?

The Fast Light Tool Kit is a cross-platform C++ GUI toolkit for
UNIX®/Linux® (X11 or Wayland), Microsoft® Windows®, and macOS®.
FLTK provides modern GUI functionality without bloat and
supports 3D graphics via OpenGL® and its built-in GLUT
emulation. It was originally developed by Mr. Bill Spitzak
and is currently maintained by a small group of developers
across the world with a central repository on GitHub.
