bug#15150: Possible bug of ln or gfortran of cygwin

[Namito]

I tried to compile following using gfortran 4.8.1-1

include 'bb/test2.f'
a(1)=1.0
a(2)=2.0
b=a(1)+a(2)
write(6,*) b
stop
end

When bb/test2.f is a real file, no compile error is generated.
When aa/test2.f is a real file and bb/test2.f is a symbolic link of
/aa/test2.f,
Error 'Can't open included file '/bb/test2.f'
is displayed.
ln -s aa bb
was a command to creat symbolic link.

The contents of test2.f is
dimension a(2)

Sincerely yours.
