Here is the output from gcc -W1,--verbose: http://rafb.net/p/UMzsPC70.html

The complete thing is very confusing to me: when I tried running gcc 
today again, the cannot find -lgcc error isn't there anymore (no 
suggestion why) and the old libxml referencing error is there again :'(

I already thought about a broken djgpp installation, but I reinstalled 
everything with new downloaded binaries from cybermirror before yesterday.
