The compilation process was easy, the main problem was only in the building of makefiles, as configure script want aclocal, autoconf, automake,autoheader and makeinfo, all of which not present on aros natively, and because of which i use my cross-compiler env (winxp/cygwin), with providing some uber line like:

Still makefile builds a bit wrong, and some tweaks was done (like chaning "gcc" on "i386-aros-gcc", adding of necessary stubs on linking stage, and remove some specific flags).

In the terms of sources, game also have some function called Sys_MakeCodeWriteable(), which use mprotect() and getpagesize() functions. And while getpagesize() aros have (in the libiberty.a), mprotect() are not, and after fast check i found that whole Sys_MakeCodeWriteable() uses only for linux, and the fast and safe way its just comment the whole function out.

Few tweaks was done in terms of networks related code (thanks to Serk) , but by some reassons its still crashes when running without -nolan option, and so, that to be fixed if it will necessary for anyone later.
