Why did you change one to sys.stdout.write but not the others?

[Jim Stichnoth, 2016/02/08 23:39:21]

The problem is:
  print 'foo', ; print 'bar'
prints 'foo bar'.  If you want to print on the same line, without an intervening
space, you have to do something like:
  sys.stdout.write('foo') ; print 'bar'

That said, I can't figure out why I don't end up with two spaces between
"#define ...TABLE" and the trailing backslash...

   print '\n'
 print "#endif // SUBZERO_SRC_ICEREGISTERSARM32_DEF",
