    Compiling main ACE project and applications.

    SYNOPSIS:

    Lots of warnings are produced when compiling the main ACE project.

    DESCRIPTION:

When compiling Ace using Visual Studio 2005 for Release|x64, I see
the following.

Hundreds of instances of the following warning for different source
files (also
when compiling applications):

..\ace/OS_NS_unistd.inl(955) : warning C4244: 'argument' : conversion
from 'ssize_t' to 'int', possible loss of data

And these other warnings:

.\SOCK_Dgram.cpp(114) : warning C4267: '=' : conversion from 'size_t' to
'u_long', possible loss of data
.\FILE_IO.cpp(135) : warning C4244: '=' : conversion from 'ssize_t' to
'u_long', possible loss of data
.\CDR_Stream.cpp(353) : warning C4267: 'argument' : conversion from
'size_t' to 'ACE_5_5_10::ACE_CDR::ULong', possible loss of data

.\ACE.cpp(2168) : warning C4244: '=' : conversion from 'ssize_t' to
'u_long', possible loss of data


When compiling an application source file, I got these warnings.
(The reference to "ecc_timer.h" refers to one of our application files.)

..\..\..\..\ace\ace/Atomic_Op_T.cpp(63) : warning C4355: 'this' : used
in base member initializer list
        ..\..\..\..\ace\ace/Atomic_Op_T.cpp(63) : while compiling class

        with
        [
            ACE_LOCK=ACE_5_5_10::ACE_Recursive_Thread_Mutex,
            TYPE=unsigned int
        ]
        ..\..\..\..\bfv.api\api.src\ecc.src\inc\ecc_timer.h(107) : see

        ]
