[Bug libstdc++/21526] New: libstdc++-v3 testsuite hangs on cygwin

["billingd at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The libstdc++-v3 testsuite hangs on cygwin on 4.0 and 4.1 branches.  The 
offending test is 27_io/basic_filebuf/showmanyc/char/9533-1.cc.  The following 
patch works around the problem and allows the testsuite to complete.

cygwin fifo support is incomplete, so this may not be a gcc bug.

I will test it on another platform overnight.
