Hi,

I think I found the same or similar problem on Windows/mingw with 64-bit build,
but it manifests while building hogweed shared dll. Here are some error lines
for reference (and for google):

C:\MinGW\msys\1.0\home\jlemm\cerbero\sources\windows_x86\nettle-2.7.1/ecc-ecdsa-verify.c:101:
undefined reference to `_imp____gmpn_copyi'
C:\MinGW\msys\1.0\home\jlemm\cerbero\sources\windows_x86\nettle-2.7.1/ecc-ecdsa-verify.c:141:
undefined reference to `_imp____gmpn_sub_n'
collect2.exe: error: ld returned 1 exit status
make[1]: *** [libhogweed-2-5.dll] Error 1
make[1]: Leaving directory
`/home/jlemm/cerbero/sources/windows_x86/nettle-2.7.1

It seems that the lib/libgmp-10.dll has no _imp_ -prefixes in the names and
nettle expects them:
$ nm lib/libgmp-10.dll | grep gmpn_sub_n
6acd7770 T ___gmpn_sub_n
6acd7817 T ___gmpn_sub_nc 

I can confirm that Kyle's solution works also in Windows: move libgmp-10.dll
from lib to bin, and rename libgmp.lib -> gmp.lib

BUT: I could not find the commit that you were referring to: was I looking at
the wrong place?
