A feature.  Though the limits on the length of the identifier that is 
required to be significant in an ISO C implementation differ for different 
classes of identifiers, there still is one for macro names.  I doubt it's 
worth implementing the precise ISO C rules (including the details of how 
Unicode characters are to be counted for each class of names) - hopefully 
there are few enough broken compilers about that people want to use GCC to 
check compatibility with.
