Um, exec_elf32.c is the problem.  Rev 1.39 of exec_elf32.c works, 1.40
doesn't.  I'm not gonna pretend to understand what the diff does, but
here's some info that may or may not help:

Also, I _don't_ need Castor's patch, for either stripped or non-stripped
binaries either:

	mona:/tmp 16> cat hello.c
	main()
	{
		printf("Hello world!\n");
		exit(0);
	}
	mona:/tmp 17> cc -o hello hello.c
	mona:/tmp 18> ./hello 
	Hello world!
	mona:/tmp 19> strip hello
	mona:/tmp 20> ./hello
	Hello world!
	mona:/tmp 21> 

Castor mentions it might be a problem with his toolchain - I'm running
with the current in-tree toolchain as of early December (egcs-1.1.1
pre-release, bintuils 2.8.1).
