Thanks Markus, that’s what
we had suspected.
In that case, is there any way
of determining whether a variable has internal or external linkage?

Hi Tom,
The c++-standard defines the static 'storage-class-specifiers'
as a piece of grammar (7.1.1). IVariable.isStatic() tells you
whether a static storage-class-specifier has been used for the
declaration of the variable.
What Microsoft refers to is defined as internal vs. external
linkage of a name. And indeed constant global variables
have internal linkage (7.1.6.1).
Note, that there is also a notion of static storage duration (3.7),
which is something different.
Markus.

Hi all,
Is it correct to say that constant global variables in C++
have static storage class? (This is suggested here: http://msdn.microsoft.com/en-us/library/0d45ty2d(VS.80).aspx.)
If so, should IVariable.isStatic() return true for such a
binding? This does not seem to be the case at the moment.
Many thanks,
Tom
