A warning prevents building because it causes GCC to ignore that whole 
declaration, causing a massive cascade of errors.  But, yes, after looking 
up more particular information on "anonymous unions", it is a feature of 
the C++ standard, not of the C standard, though as much as I have read, the 
standard does not restrict that behavior, it seems it was just a change of 
mind of the GCC developers to disable this behavior for C code.  Sad 
really, since it improves the readability of code greatly.
