Hey, I was in Paris playing on my sister's computer! :)
C's rules on static local variables are similar to C++. The thing to
note is that C does allow initializers that do work. You could write
void foo()
{
static int x = bar();
}
In that case, x is like a global variable that can only be seen inside
foo, but it can't be initialized until foo is entered. If the
initializer was a constant expression, it could be part of the
initialized data, but otherwise, its value is indeterminate until the
first entry to the function (or scope) containing it.
Note: in the case above, x would only be initialized on the first entry
to foo(). This implies that the compiler has to store a second,
initialized global, that is used to track the initialization of the
first. A smart compiler will eliminate this if its able to initialize
the variable from a constant expression.
