empty function macros

[Alexander Best]

hi there,

i noticed freebsd has a few of the following macros:

#define FUNC(sb)

when you do something like

if (cond)
    FUNC(i)

the compiler complains about an if statement with an empty body. any sensible
way of dealing with this issue?

i saw some reiserfs code which does the following to silence compilers:

#define FUNC(sb) do { } while (0)

cheers.
alex
