commit 40a7bdf50e19faaf106470897fed72af623adc50
Author: Werner Koch <wk at gnupg.org>
Date:   Fri Jan 30 16:58:02 2015 +0100

    w32: Use -static-libgcc to avoid linking to libgcc_s_sjlj-1.dll.
    
    * src/Makefile.am (extra_ltoptions): New.
    (libgcrypt_la_LDFLAGS): Use it.
    --
    
    Since gcc 4.8 there is a regression in that plain C programs may link
    to libgcc_s.a which has a dependency on libgcc_s_sjlj.dll.  This is
    for example triggered by using long long arithmetic on a 32 bit
    Windows (e.g symbol __udivdi3).
    
    As usual the gcc maintainers don't care about backward compatibility
    and declare that as some kind of compatibility fix and not as
    regression from 4.7 and all earlier versions.
