No, that's just because of the way msvc handles imports.
In fact the variable is a BOOLEAN, you just treat it as PBOOLEAN when
you import it from your driver.
A correct definition would be "__declspec(dllimport) BOOLEAN
Mm64BitPhysicalAddress;", which would internally be treated as a
reference to "_imp__Mm64BitPhysicalAddress", which is a pointer to the
real variable stored in ntoskrnl. This way it must be handled on gcc.
