All .a libraries were converted to .la, and instead of linking the Xorg binary with a mix of .a and .la, and adding some libraries more then once in the command line, etc, now it generates a single libxorg.la from all the required convenience libraries, and links with a dummy xorg.c (that should usually be the file with the main function...). This removes the requirement of some things like libosandcommon and libinit, that existed to circumvent problems when linking multiple .a and .la in the final Xorg binary. The "symbol table" is now generated dynamically, by a shell script, with an embedded gawk parser that parses cpp output. The new file sdksyms.sh is generated by hand by analyzing all Makefile.am's and making it create a sdksyms.c file, that includes all sdk headers that will add symbols for the Xorg binary. Module headers aren't read, and a in 2 files it was required to add a "<hash>ifndef XorgLoader" around declarations shared between the Xorg binary and libextmod. A few other changes were added to other sdk headers, like preventing multiple inclusion, or including other headers to satisfy dependencies. This should be a lot more portable, and better (hopefully properly) using libtool to generate convenience libraries.
