Bug 99694

Created attachment 124867 [details]
Modified gifread.cxx

Sorry to post as bug rather than submit change via gerrit, I haven't tried to register yet until I get some confidence I can build x64 on Windows with VSC2015.

Warning treated as Error by Visual Studio Community 2015, result of 32-bit shift implicitly converted to 64 bits (was 64-bit shift intended?)

The result of 32-bit shift was implicitly converted to 64-bits, and the compiler suspects that a 64-bit shift was intended. To resolve this warning, either use 64-bit shift, or explicitly cast the shift result to 64-bit.

This prevents compiling x64 from source, but the same can be compiled OK for x86.

Following Microsoft recommendation :-
