I should have looked at this more carefully: indeed it's in that directory, 
because that's where we have put it...

Sorry about this.  I'm installing the following fix.  Cheers!

commit 28369ecb5d4184f4bed8cccd9e8e018a3d985c75

    tests: avoid creating files whose name collide with standard headers
    Having a file named "exception" is risky: the compiler might use that
    file in #include.
    Reported by 马俊 <address@hidden>.
    * tests/local.at (AT_SKIP_IF_EXCEPTION_SUPPORT_IS_POOR): Generate
    'exceptions', not 'exception'.
