lchmod cygwin failure

[Simon Josefsson]

Building in cygwin fails because:

depbase=`echo test-fcntl-h-c++.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
        g++ -DHAVE_CONFIG_H -I.  -I. -I. -I.. -I./.. -I../gllib -I./../gllib    
-MT test-fcntl-h-c++.o -MD -MP -MF $depbase.Tpo -c -o test-fcntl-h-c++.o 
test-fcntl-h-c++.cc &&\
        mv -f $depbase.Tpo $depbase.Po
In file included from ../gllib/fcntl.h:41,
                 from test-fcntl-h-c++.cc:22:
../gllib/sys/stat.h:668: error: ‘lchmod’ was not declared in this scope
../gllib/sys/stat.h:668: error: invalid type in declaration before ‘;’ token
make[3]: *** [test-fcntl-h-c++.o] Error 1

(Not sure how the broken UTF-8 characters happened..)

Any ideas?

checking for lchmod... no
checking whether lchmod is declared without a macro... no

Line 668 is the '_GL_CXXALIASWARN (lchmod)' call below.
