Sample code to illustrate windres resource alignment problem

Hello,

I've just noticed this problem with windres (gave me a bit of a hardtime to
understand the problem).

The resource compiled with windres are not aligned.

Despite this https://sourceware.org/bugzilla/show_bug.cgi?id=16065 

I'm not sure what this code does. But it does not seem to align the resources.
This would not be a big problem if it did not break some resources. For
instance dialogs with combo box control that are not 32-bit aligned won't open
properly (possibly some other controls). It's tricky enough as it does not
generate any kind of error. Windows will just send a premature WM_DESTROY
before the WM_INITDIALOG.

I had a quick look at the source code. The easiest way to fix the problem seems
to force the alignment in the binutils/resbin.c:res_to_bin() function. I've
tried that and it worked but I did not watch the whole code in depth so I'm not
sure it has any unexpected side effect.

I've attached a little program to demonstrate the problem.

Best regards,
G.B
