gcc issued lots of warnings if compiled with -Wundef. This shows access
to undefined preprocessor macros, particularly for config tests.
This update is similar, but not identical to fltk-cpp-fixes.patch as
posted on STR #2988 (file #1). There have been changes in the configure
script and the macros in configh.in and configh.cmake.in meanwhile.
This commit compiles with -Wundef w/o such warnings under Linux and
Windows (MinGW).

The old behavior is retained, but the files have been modified
to match the new versions in the porting branch as much as possible.
The porting branch has its own (modified) version. Windows executables
built with the new IDE's (generated by CMake) don't have the trailing 'd'
in Debug mode.

CMake versions 3.4.x crash when using fltk_wrap_ui, a built-in CMake
command. According to the CMake devs this will be fixed in CMake 3.5.
However, since fltk_wrap_ui is no longer necessary (it can replaced by
custom build commands) and some Linux distributions deploy CMake 3.4.x
we decided to use an own replacement function.
This makes sure that FLTK can be built with CMake 3.4.x, but FLTK users
may still have to rewrite their own CMake files to not use fltk_wrap_ui.

First step towards a hopefully clean creation of FL/abi-version.h for all
Windows (Visual Studio) and maybe also Xcode projects (if necessary) in
order to "simulate" configure and CMake methods to create this file.
I could only modify the VisualC2008 and VisualC2010 project files, because
I don't have VisualC6 and/or Xcode. Help needed...
To do for remaining <ide> directories (ide/VisualC6 and maybe ide/Xcode4):
(1) Remove <ide>/FL folders including <ide>/FL/abi-version.h.
(2) Add a Pre-Build event or equivalent on project 'fltk' for all
potential build configurations (Debug, Release, ...)
(3) Maybe add project dependencies to ensure that the Pre-Build event
of project 'fltk' is executed before all other projects.
Notes:
(a) Command line for Pre-Build events of VS2008/2010:
"copy /Y $(SolutionDir)..\..\abi-version.ide $(SolutionDir)..\..\FL\abi-version.h"
Something similar should work for VC6 as well.
(b) While building the projects I found some wrong output settings in zlib
projects. These have been fixed in this commit as well (unrelated).
(c) .gitignore has been extended to ignore all intermediate build files
of VS2008/VS2010 ide projects.

because it did not use the correct dwmapi.dll - based implementation.
This commit uses the correct way to compute the width and height of window
borders in Fl_Window::decorated_h() and in Fl_Paged_Device::draw_decorated_window().
2) Fixed the computation of enhanced metafile units that correspond to a given pixel size
used by the Fl_Copy_Surface class on the WIN32 platform.
Tested with MSWindows XP, 7 and 10 using the device test app.

on the MSWindows platform, for consistency.
2) Slightly improved Fl_Image_Surface::draw_decorated_window() under WIN32.

This gives the same drawing capabilities to all supported drawing
surfaces: display, printer, clipboard, in-memory bitmap image,
PostScript file.
Also, completed the Mac OS implementation of
Fl_Copy_Surface::draw_decorated_window(Fl_Window *win, int delta_x=0, int delta_y=0)
that did not honor non-zero last arguments.

This matches the recent support of the --enable-x11 option
by the configure script on the mac.

This commit makes the file config.h generated by CMake 100% compatible
with the one generated by autoconf/configure.
Fixes in this commit:
- Set FLTK_DATADIR and FLTK_DOCDIR with the same default values.
Note: needs some cleanup, option values are not clear, '/fltk'
is currently appended in export.cmake (needs improvement).
- Simulation of autoconf macro AC_HEADER_DIRENT for correct
definition of only one 'dirent' header file.
- Fix more function checks:
- dlsym
- png_get_valid
- png_set_tRNS_to_alpha
- Improve "Big Endian" check for __APPLE__ (mac_endianness.h).

The files "config.h" generated by configure and CMake are now almost
identical, except a few comments and some still missing or failing
config tests, for instance checks for some functions in libraries.
[Note: tested and compared on Linux.]
configh.cmake.in: Fixed many #cmakedefine and #cmakedefine01 statements
so they #define their variables as 0 or 1, or /* #undef */ it, resp.,
as it is done in the configure build.
Added tests:
- libXrender
Fixed tests:
- function glXGetProcAddressARB
Todo (still failing tests in CMake):
- HAVE_PNG_GET_VALID
- HAVE_PNG_SET_TRNS_TO_ALPHA
- HAVE_DLSYM
Other remaining issues:
- compiler flags introduced in configure/make build
- HAVE_SYS_NDIR_H - maybe missing test in configure ?
- HAVE_SYS_DIR_H - maybe missing test in configure ?
- HAVE_NDIR_H - maybe missing test in configure ?
- WORDS_BIGENDIAN and #include <mac_endianness.h> ...
i.e. Mac OS X specific #include needed or not ?

Configure and CMake now both check if X11/Xregion.h exists on the
build system and set HAVE_X11_XREGION_H in config.h accordingly.
src/Fl_Pixmap.cxx: modified to use the configure test as proposed by Manolo

done both for the configure/make and the CMake build systems
(the Xcode build system did that already).

1) Changed the way fluid attaches images to widgets and menu items so
it is compatible with running fluid-generated code containing such images
in a static initializer. Images are now attached calling a function:
widget->image( image_function_name() );
and this function is defined before in fluid-generated code as:
static Fl_Image *image_function_name() {
static Fl_Image *image = new image_type(......);
return image;
}
2) Changed src/Fl_File_Chooser.fl so the source code generate by fluid
from it is compatible with running in a static initializer.
3) Changed src/Fl_File_Chooser.cxx and FL/Fl_File_Chooser.H
to the result of running fluid on src/Fl_File_Chooser.fl

To make sure that fl_graphics_driver is initialized, it is enough to test whether it is null.
This saves the memory cost of a static variable.
