6df4bd8f8c Fix a few more warnings 
Some are important, e.g. the seemingly harmless braces around if with dprintf,
since that dprintf is defined as empty, will screw things up and grab the next
line

aaa246f86f mcexec: change debug printf macros to be more tolerant to trivial format

but this is just as generic and we can now use dprintf everywhere
