Sebastian Geiger commented on LOGCXX-490:
-----------------------------------------
Hi,
using `while(!true)` gives the same result. I researched this a bit further and
it seems that this is a common idiom in C++ and the problem is rather that the
MSVC compiler should not treat it as a warning. According to the below link,
this was fixed in MSVC2015 but I am still using MSVC2013 so I guess I will just
disable the warning until I get a change to upgrade to a newer visual studio
version
Sorry for the noise and thanks a lot for the fast response.

> Project: Log4cxx
> Issue Type: Improvement
> Reporter: Sebastian Geiger
> Priority: Minor
>
> When I activate the /W4 warning level in MSVC 2013 I get the following
> warning:
> warning C4127: conditional expression is constant
> The warning appears for all statements that use the LOG4CXX_* macros suchas
> LOG4CXX_ERROR. I currently get more than 500 if these warnings, which makes
> identifying more important warnings rather difficult.
> Of course I could disable the warning, but if this is something that could be
> fixed in the log4cxx code then I think that would be a better solution.
