 Ok, but our default compiler thinks so and fails on an important part
 of pkgsrc infrastructure. But this works on NetBSD current i386:
 
 export CFLAGS=-fno-strict-aliasing 
 ./testbootstrap 
 
 
 I will try to check the gcc bug lists and otherwise create a small test
 example to get this resolved in gcc. Otherwise this will hit us again.
 I stumbled over this kind of problem before and suitable aligning shorts
 and ints made all compilers happy. But I apologize for too quickly
 blaiming the code. Anyway, using -fno-strict-aliasing somewhere in the
 Makefiles for gcc solves this problem. 
 
 Have a nice day,
 
 Kai-Uwe
