Aha, thanks for this tip, I found an incantation that works:
```
CC=x86_64-w64-mingw32-gcc \
CC_FOR_BUILD=x86_64-linux-gnu-gcc \
CPPFLAGS=-D__USE_MINGW_ANSI_STDIO \
LDFLAGS="-static-libgcc -static-libstdc++" \
./configure \
--build=x86_64-linux-gnu \
--host=x86_64-w64-mingw32 \
--enable-fat \
--enable-static \
--disable-shared \
--prefix=/home/claude/wintmp/
```
The `CPPFLAGS` is necessary to avoid test failure in printf/scanf.
That's a known problem, maybe it should somehow be enabled by default by
gmp's configure, but I don't fully understand the implications.
Not sure why the setting of LDFLAGS and CC_FOR_BUILD are needed though,
can you explain?
LDFLAGS is just personal preference so I can ship my final program
without DLL dependencies, I don't know if it is necessary or even has
any effect for static .a libraries.
CC_FOR_BUILD is necessary otherwise the configure fails because it uses
the wrong build system compiler:
```
$ CC=x86_64-w64-mingw32-gcc CPPFLAGS=-D__USE_MINGW_ANSI_STDIO
LDFLAGS="-static-libgcc -static-libstdc++" ./configure
--build=x86_64-linux-gnu --host=x86_64-w64-mingw32 --enable-fat
--enable-static --disable-shared --prefix=/home/claude/wintmp/
