not quite.  GCC allows __attribute__((__const__)) or 
__attribute__((__pure__)), to declare that, though (one of 
them allows reading global variables, the other doesn't, I 
forget which).  In C and C++ per standard, "const" can only 
be applied to types, e.g. function arguments (including 
C++'s implicit *this, via funny location of "const").  Maybe 
C99 made up an additional way to use it, as it introduced 
"restrict", I forget
