The trick is that if you're using configure and you don't want to have SDL_config.h and SDL_revision.h to show up as modified, you need to configure and build from a separate directory.
You also need to include SDL_revision.h directly if you want to use the SDL_REVISION constant, as a side effect of these changes.

rename : include/SDL_config.h.default => include/SDL_config.h
The configure script was breaking the substitutions into multiple fragments, breaking them across the substitution for the build rules. This of course totally hosed the process.
I switched to using a more modern usage of AC_OUTPUT and added a post-process step that appends the build rules to the Makefile.
This patch significantly speeds up make process (mostly noticeable on MinGW+MSYS) canceling implicit rules for dependencies and Makefile.in that caused lot of unnecessary file checks (in case of Windoze those are pretty slow). See "make -d" before and after applying this patch.

When trying to run a parallel build, gcc will not be able to find SDL_revision.h

On my linux box it compiles and installs correctly and testatomic runs without errors.

Subject: Re: About QNX support in SDL 1.3
Here is another batch of patches.
1) Makefile.in - added SDL_opengles.h header as header to install.
2) configure.in - Added special define to detect Common Lite OpenGL ES
library in case if Common library is not installed. Added check for
clock_gettime in libc (in QNX it is in libc).
3) SDL_config.h.in - Added SDL_VIDEO_RENDER_OPENGL_ES and
SDL_VIDEO_OPENGL_ES declarations for configure script autodetection.
4) SDL_opengles.h - Added GL_API definition if it is not defined. Added
extension GL_OES_draw_texture because OpenGL ES Renderer uses it without
declaration. Added GL_OES_vertex_buffer_object extension, which is supported
under QNX OpenGL ES. Added GL_OES_single_precision extension.
5) To the test directory I've added building OpenGL ES test applications
through the autotools suite. Was support for iPhone IDE building only.
