No, you can't rest easy with this initialization since it is quite
illegal in C.  The value of a global initializer must be a constant
expression, which this is not since it involves the value of the
variable x (which happens to be of type "const int").  It is legal
in C++, of course.  Whether particular C and C++ compilers will work
together is a matter to discuss with your compiler vendors.  Not
all C compilers for a given machine will work together.
