After gathering information from the CrossGCC FAQ and from this list, I successfuly built a 68k cross-compiler (the compiler works, but I haven't tried out the library yet). Here is the script I used; it is not very elegant and it uses up a lot of space, but it seems to work fine, both on Linux redHat 6.0 and on CygWin (CygWin tends to slow down to a trickle on Windows 98, but that is another problem). It would be a good idea to delete the "build" subdirectories at the end of the process (or to modify the script to use a single "build" directory if space is tight).
