I present you with a comment near a similar macro (SVN_ERR) used in
Subversion.
/* The `do { ... } while (0)' wrapper has no semantic effect, but it
makes this macro syntactically equivalent to the expression
statement it resembles. Without it, statements like
if (a)
SVN_ERR (some operation);
else
foo;
would not mean what they appear to. */
