[Coin-discuss] MSV pragma

[Matthew Galati]

FYI. I was able to get a clean MSVS8 build by disabling the following warnings in the following projects.

For the most part, they look harmless and are probably ok to ignore. But, that is up to each developer to determine.

Can we, fix the warnings that are not safe, and either:
 (a) add /wd flags to each MSVS project workspace,
 (b) have each project add a pragma file disabling the approriate warnings?

Thanks,
Matt

Examples of each:

At a glance, probably ok to ignore:

Warning	1	warning C4290: C++ exception specification ignored except to indicate a function is not __declspec(nothrow)	c:\cygwin\home\magala\coin\coin-decomp\alps\src\AlpsEncoded.h	111

Might not want to ignore?

When built in MSV, several COIN projects trigger warnings C4290/C4996. I am fine ignoring them, but can we get them disabled? In my project, I do it in my DecompConfig.h. But, my project depends on several other COIN projects - so I get a very messy build log when building the deps. 

Can we somehow add these across the board? Maybe putting them in CoinPragma.hpp? Although I am not sure all projects include CoinPragma.hpp.

Thanks,
Matt
