+[Altertatively you can run make startup in the top level build dir]
+
+Autoconf is configured to do some basic system probes for optional and 
+required functionality and generate an environment.mak and include/config.h 
+from it's findings. It will then write a 'makefile' and run make dirs to 
+create the output directory tree.
+
+It is not my belief that autoconf should be used to generate substantial 
+source code markup to escape OS problems. If an OS problem does crop up 
+it can likely be corrected by installing the correct files into the 
+build include/ dir and perhaps writing some replacement code and 
+linking it in. To the fullest extent possible the source code should conform
+to standards and not cater to broken systems.
+
+Autoconf will also wite a makefile into the top level of the build dir, 
+this simply acts as a wrapper to the main top level make in the source tree.
+There is one big warning, you can't use both this make file and the
+ones in the top level tree. Make is not able to resolve rules that 
+go to the same file through different paths and this will confuse the
+depends mechanism. I recommend always using the makefiles in the
+source directory and exporting BUILD.
