Build failure under Cygwin_NT-5.0

[Paul Thomas]

I applied Danny's patch and got to:

al/include -I/usr/local/include \
../../gcc/gcc/config/i386/winnt.c
../../gcc/gcc/config/i386/winnt.c: In function `i386_pe_mark_dllexport':
../../gcc/gcc/config/i386/winnt.c:286: warning: implicit declaration of 
function
 `DECL_NON_ADDR_CONST_P'
../../gcc/gcc/config/i386/winnt.c:286: error: invalid lvalue in assignment

make[1]: *** [winnt.o] Error 1
make[1]: Leaving directory `/cygdrive/d/gcc-cvs/build/gcc'
make: *** [all-gcc] Error 2

I tried to copy the symbian version of the patch by eliminating all mention 
of DECL_NON_ADDR_CONST_P, winnt.c then compiled but the build bombed out in 
varasm.c for the same reason.

Since I haven't the slightest idea of what I am doing, I left it there!
