Hi,

I've updated my current project with the last curlpp available version, and
my Visual C++ 7.1 throwed me a strange warning while compiling.

It came with the "ConnectTimeout" option, but I think it could come from any
other "long" option.

Let me print here the warning :
---------------------------------------------------------------------
e:\SRC-DEV\_V2\include\curlpp\OptionSetter.inl(37) : warning C4312: 'type
cast' : conversion from
'cURLpp::OptionSetter<OptionValueType,optionType>::ParamType' to 'void *' of
greater size
with
[
OptionValueType=long,
optionType=CURLOPT_CONNECTTIMEOUT
]
C:\Visual Studio .NET 2003\Vc7\include\vector(140) : while compiling

with

optionType=CURLOPT_CONNECTTIMEOUT
]

template instantiation 'cURLpp::OptionSetter<OptionValueType,optionType>'

E:\SRC-DEV\_V2\include\boost\date_time\int_adapter.hpp(49) : while compiling

]
CWebSeed.cpp(348) : see reference to class template instantiation
'cURLpp::OptionTrait<OptionType,option>' being compiled

---------------------------------------------------------------------

As you can see, VC++ likes to repeat the same warning.
Anyway, the important thing is that it came with a change you made in the
"OptionSetter.inl" file :
a (void*) cast !!!

here :
template< typename OptionValueType,
cURL::CURLoption optionType >
void
cURLpp::OptionSetter< OptionValueType,
optionType >::setOpt(cURLpp::CurlHandle *handle,
ParamType value)
{
handle->option(optionType, (void *)value);
}
(and other overloads...)

Setting back with no C-like cast suppresses the warning.
Did a mistake was made ? Is this intended ?

Just to make my mind clear.
