It does for me (well, non-_[_A-Z] names; things such as _LP64 are also in 
the reserved namespace).  There's 
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=545> for a limited number of 
cases where such macros are defined from specs (that check textually for 
the -ansi option, instead of for flag_iso as set inside cc1), but the bulk 
of cases of that were fixed long ago.
