texinfo 4.8: make check fails no-headers test on Cygwin

[Keith Marshall]

Hi,

Having recently built texinfo 4.8 on a two year old Cygwin installation, 
`make check' failed one test, viz. `no-headers';  otherwise, no other 
problems were observed, and all appears to work correctly.

The failure of `no-headers' appears to be due to the use of `-o /dev/null' in 
the makeinfo command -- seemingly Cygwin is mishandling this, since 
substitution of `-o nul', (or indeed, any non-special file name), allows this 
test to pass.

Attached patch, against CVS HEAD on savannah.gnu.org, adapts the test to work 
around the Cygwin problem, with no effect on platforms on which it already 
passes successfully.  (The tarball includes the patch file, and a proposed 
ChangeLog entry, as a separate text file).

Best regards,
Keith.
