Cross-compiling for Windows: redefinitions unilbrk-related

[Michele Locati]

I'm cross-compiling gettext 0.21.1 with mingw.

I configure it with:

./configure --enable-relocatable --prefix=/gettext --disable-shared \
    --enable-static --quiet --enable-silent-rules \
    --host=x86_64-w64-mingw32.static --config-cache \
    --disable-dependency-tracking --disable-java --disable-native-java \
    --disable-csharp --disable-rpath --disable-openmp --disable-curses \
    --without-emacs --disable-acl --enable-threads=windows \
    --with-included-libxml --without-bzip2 --without-xz \
    ac_cv_func__set_invalid_parameter_handler=no \
    CPPFLAGS="-D__USE_MINGW_ANSI_STDIO=0 -Wno-int-to-pointer-cast
-Wno-attributes -Wno-write-strings -g0 -O2 -DLIBXML_STATIC"

I got a bunch of warnings about redefinitions related to unilbrk:
