Re: [ros-dev] [ros-diffs] [hbelusca] 62562: [EXT2] try_return() == try_return(S) with nothing in S . The code sometimes use it. Shut up MSVC warning C4003: not enough actual parameters for macro 'try_return'.

[Thomas Faber]

That's illegal, macros can't be overloaded.
drivers/filesystems/ext2/inc/ext2fsd.h:64:0: warning: "try_return" redefined
[enabled by default]
You could try
#define try_return(...) { __VA_ARGS__; goto try_exit; }
If that doesn't do it, it might simply need a separate macro
(I'm not sure to what extent this is third party code though)
(also if these were the last instances of that -- and I think so --, we
might want to make 4003 an error)
