Patch to make leJOS compile with gcc4

When I was trying to build leJOS on Mac OS X Tiger 10.4.3 with gcc4 (from Xcode 2.2):

$ gcc_select
Current default compiler:
gcc version 4.0.1 (Apple Computer, Inc. build 5247)

I was getting this error:

====> Making leJOS Unix binaries (lejos, for emulation)
cd unix_impl; make OSTYPE=darwin
gcc -I../vmsrc -I. -Wall -Wno-unused -c ../vmsrc/threads.c
../vmsrc/threads.c: In function 'switch_thread':
../vmsrc/threads.c:326: error: label at end of compound statement
make[1]: *** [threads.o] Error 1
make: *** [tinyvm_emul] Error 2

This is simple to fix by applying this patch:
