Macros with multiple statements should be enclosed in a do - while block:
.. code-block:: c
#define macrofun(a, b, c) \
do { \
if (a == 5) \
do_this(b, c); \
} while (0)

We're declaring functions not inlining executable code.Hi,
It makes sense, thanks for the insight. Please drop this patch
Thanks
