I've re-run Wine's tests with a new clean VM environment and some 
changes to include more tests and similar results:

Compiler                                         Failures
gcc-4.9.4:                                       39
gcc-7.1.0:                                       78
gcc-7.1.0-patched (with -mcall-ms2sysv-xlogues): 40


The first error not present in the gcc-4.9.4 tests that I examined 
looked like a run-of-the-mill race condition in Wine that just happened 
to not crash when built with 4.9.4.  So I'm going to guess that the 
disappearance of these failures with -mcall-ms2sysv-xlogues is just 
incidental.  I think we're in good condition with this patch set.
