Build Update for OpenSmalltalk/opensmalltalk-vm
-------------------------------------

Build: #1531
Status: Passed

Duration: 55 mins and 11 secs
Commit: 14b6d36 (Cog)
Author: Nicolas Cellier
Message: Fix suspiscious logical construction

In code we find this flag:

    #define SOCK_BOUND_UDP     0x00040000

and test of this flag in socket state:

    if(pss->sockState & SOCK_BOUND_UDP)

We also find the negation:

    if(!pss->sockState & SOCK_BOUND_UDP)

But there is a precedenc eproblem in above expression, as reported by the compiler

    ../../platforms/win32/plugins/SocketPlugin/sqWin32NewNet.c:872:8: warning: logical not is only applied to the left hand side of this bitwise operator [-Wlogical-not-parentheses]
        if(!pss->sockState & SOCK_BOUND_UDP) {
           ^               ~
    ../../platforms/win32/plugins/SocketPlugin/sqWin32NewNet.c:872:8: note: add parentheses after the '!' to evaluate the bitwise operator first
        if(!pss->sockState & SOCK_BOUND_UDP) {
           ^
            (                              )
    ../../platforms/win32/plugins/SocketPlugin/sqWin32NewNet.c:872:8: note: add parentheses around left hand side expression to silence this warning
        if(!pss->sockState & SOCK_BOUND_UDP) {
           ^
           (              )

Above code is interpreted as  `if( (!pss->sockState) & SOCK_BOUND_UDP)` which does not mean much...

Please, read C compiler warnings, they are a companion tool !
