gcc trunk failure, bad regeneration of plural.c

[Tim Prince]

When building gcc trunk on cygwin64, it runs bison to make a new copy of
intl/plural.c, which leads to failure.  If I copy the plural.c which
came from svn to the build directory, it all runs fine.  Is this expected?
The gcc testsuite the last few weeks quits early with a pipe failure,
and the libgomp test appears to try to configure for a 32-bit target, so
also fails.  g++ testsuite seems to test some non-existent debug
format.  Otherwise, test suites seem to run as well as could be
expected.  There are rounding tests in gfortran which seem to depend on
x87 settings which differ from expectation in X64, so that's not a
problem with the compiler.
