2.95.2 didn't handle the differences between C89 and C94.  3.0 does; in 
particular, the default version is gnu89, which has been clarified to be 
C89, plus GNU extensions, which include digraphs from C94 but not the %ls 
%lc %l[ printf/scanf formats (so -pedantic, with no other standard option, 
will warn about those, which I think is the most useful behaviour for now 
for those users, such as GCC itself, of -pedantic without -std).  C89 
didn't include __STDC_VERSION__, so it is no longer defined by gnu89.
