Ah, your right. This seems to work. Shouldn't have blamed automake for
this, then.

Do you think it would make sense to somehow have TESTS_ENVIRONMENT
*default* to wine, for this type of cross builds?

As I said, I haven't yet installed any 64-bit enabled wine. I don't
doubt that w32 builds work, I have just have never tested that, and I
think it helps if it can be easily tested without the need for a windows
box or d:o license. Are there any w32 tests in the nightly builds? Using
wine makes that easy, even if that's not a 100% substitute for testing
native builds.

I just tried a

  ./configure --host=i586-mingw32msvc --enable-fat && make && make TESTS_ENVIRONMENT=wine check

It turns out I get two failures, appearantly *not* fat-related, since my
non-fat w32 build has the same problem:

make[4]: Entering directory `/home/nisse/build/gmp-w32-fat/tests/misc'
gmp_vsnprintf return value wrong
  fmt       |%Md|
  bufsize   0
  got       |!0|
  want      ||
  want full |0|
  ret       13
  want_len  1
FAIL: t-printf.exe
../../../../hack/gmp/tests/misc/t-scanf.c:1495: GNU MP assertion failed: ret == (-1)
FAIL: t-scanf.exe

Could of course be a bug in wine, if these tests succeed on native
windows.
