Spelling fixes round 6 - resend - don't apply first patch

[Francois Gouget]

 #ifdef HAVE_UNISTD_H
-# include <unistd.h>
+#include <unistd.h>
 #endif
 #include <stdarg.h>
 #include <stdio.h>

I think this chunk should not be applied because:
 * as pointed out before, it's not a spelling fix
 * it's perfectly valid to have a space there
 * the indentation makes the scope of the #ifdef clearer. So removing it 
makes the code less readable
