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'.

[Sylvain Petreolle]

I checked the original source from http://sourceforge.net/projects/winext2fsd/.

try_return(S) with nothing in S are ours exclusively. those are to be fixed instead.


 
Kind regards,


Sylvain Petreolle

with nothing in S . The code sometimes use it. Shut up MSVC warning C4003: not enough
actual parameters for macro 'try_return'.
 

I took the warning form the GCC builder.
Looks like it should be C4005 on MSVC though.
Shouldn't you have seen that when you built it? ;)


Hmm, also, ext2 has allow_warnings for some reason (which is why this
even builds). We should really remove them all, only ntdll_winetest
should need one at this point.
