Syslinux - Mar 2016 - [PATCH 3/5] installers: MSVC compatibility fixes

More MSVC compatibility fixes, for packed structures.
NB: In case you are aware of the issues that may come with MS vs GCC 
packing, so far, I have not seen evidence of detrimental impact from 
using ms_struct packing in MSVC (vs gcc_struct, which is explicitly 
specified for MinGW), with regards to the sections of code I am using in 
Rufus.

Did Visual Studio actually complain about this one?

WDK compiler (which I also use) if I recall correctly. At any rate, some 
older compilers do not like double initializations like this one, and I 
don't think this change should be much of a contention point, since it 
doesn't introduce any liability.
