| Subject: Re: [boost] Supressing warnings
| In my opinion, a major problem with paying
| attention to warnings and changing the code in order
| to prevent warnings is, that in this way the code
| is not only written for a *special compiler*, but
| even **for a special compiler version**.
| I don't think that this is good practice.
| More and more people realise, that the code "should
| speak the truth", but code can be obfuscated by trying
| to prevent compiler warnings (for some special compiler,
| in some special version).
What about the MSVC warning 4127?
# pragma warning(disable: 4127) // conditional expression is constant.
No amount of recoding can help with this can this - a constant conditional
expression is exactly what one was trying to achieve!
What are you suggesting for this?
Doing nothing is not an option, if you accept my premise that a -pedantic or
MSVC level 4 compile without warnings is what we want.
What mechanism for supressing it is best?
| Having said this, in my experience gcc, version 4.1 or later,
| with "-ansi -pedantic -Wall" works quite well.
Does it produce a "conditional expression is constant" warning?
(Or similar generally unhelpful messages).
How can you stop it?
