This I do/have tried, but it still picks the gcc and not the arm-linux-gcc.

Thats my intention, or at least I will run on both Linux PC and embedded 
Linux.

I understand that './configure --host arm-linux' should do the trick, 
but I cant get this to work on any other things than the example 
following the development kit. But the configure file is 144kb so I dont 
 feel like going thru that file.

When I make my own Makefile manually it works ok (see below).
So something must be wrong with the way I build my configure file, or 
somthing is wrong on my system so ./configure ignore the
--host arm-linux (which is a bit strange since it works on the example file)

I've tried to change the path and make links e.g. gcc = arm-linux-gcc, 
so that when somthing asks for gcc it gets the arm-linux-gcc, this work 
to some extent, but also gives a lot of problems, and it's NOT the way 
to do things proper.

Will be happy for any info/tips/help. Been searching the net and reading 
documentatin for weeks, but dosnt seem to get any further by my own.

Using WinCE and pay some $$ to Bill is starting to sound like a way out 
:) ugh   did I say that?
