Details:

Cygwin does provide newlocale function, thus @HAVE_NEWLOCALE@ = 1.

But <locale.h> does declare locale_t only if selected by feature macros,
causing this compiler error when using libintl.h with -std=c90:

<code>
$ x86_64-pc-cygwin-gcc -std=c90 -O2 -pipe -O2 -pipe -I./subversion/include
-I./subversion -I/usr/include/apr-1 -I/usr/include/apr-1 -I/usr/include/serf-1
-c subversion/libsvn_delta/compat.c  -DDLL_EXPORT -DPIC -o
subversion/libsvn_delta/.libs/compat.o
In file included from ./subversion/svn_private_config.h:255:0,
                 from subversion/libsvn_delta/compat.c:36:
/usr/include/libintl.h:440:8: error: unknown type name 'locale_t'
 extern locale_t newlocale (int, const char *, locale_t);
        ^
