patch for (clang) problem on Cygwin 1.7.28(0.271/5/3) i686

[Urs Janßen <tin at akk dot org>]

Here's a log-entry from a configure (autoconf) script (when looking for
ncursesw):

configure:9503: clang -c -g -I/usr/lib/gcc/i686-pc-cygwin/4.8.2/include -O0
-std=c99 -pedantic -W -Wall -Wextra -Wcast-align   -D_XOPEN_SOURCE=600
--I/usr/include/ncursesw conftest.c 1>&5

configure: failed program was:
#line 9496 "configure"
#include "confdefs.h"
#include <curses.h>
int main() {
initscr(); tgoto("?", 0,0)
; return 0; }


After applying the attched patch, configure runs as expected. I'm not sure
if it's the right approach to fix the issue. IIRC the issue was not present
in cygwin 1.7.27.

HTH,
