Linking against 3.4.10 libgnutls.a file:

.../lib/libgnutls.a(sha256-ssse3-x86.o): warning: common of
`_gnutls_x86_cpuid_s' overriding smaller common
...lib/libgnutls.a(x86-common.o): warning: smaller common is here

declarations appear to be here:

lib/accelerated/x86/x86-common.c
49:unsigned int _gnutls_x86_cpuid_s[3];

lib/accelerated/x86/coff/sha256-ssse3-x86.s
67:	leal	__gnutls_x86_cpuid_s-.L001K256(%ebp),%edx
3400:.comm	__gnutls_x86_cpuid_s,16

perhaps the comm directive redefines it, or perhaps that's just under
mingw that it does?

gnutls-3.4.10 $ i686-w64-mingw32-gcc-nm -a
./lib/accelerated/x86/x86-common.o | grep _gnutls_x86_cpuid_s
0000000c C __gnutls_x86_cpuid_s

gnutls-3.4.10 $ i686-w64-mingw32-gcc-nm -a
./lib/accelerated/x86/coff/sha256-ssse3-x86.o | grep
_gnutls_x86_cpuid_s
00000010 C __gnutls_x86_cpuid_s

FWIW.
Thanks!
