That's true, but the implementation isn't just GCC, it is also C libraries
which aren't provided by GCC.  Including a character (if possible) that
will make it unaccessible from C/C++ is desirable.  And, not changing the
names of non-TREE_STATIC vars is also desirable, those I'm afraid show up
in the debug info from time to time, so making them unnecessarily larger
results in .debug_info size increases.
