[Bug c/39605] New: "error: variable-size type declared outside of any function" is issued twice

[gerald at pfeifer dot com]

The following snippet

  #define FIRST ((void*)0x80)
  #define LAST  ((void*)0x86)

  static int b[LAST-FIRST];

now (2009-03-31) generates the following compiler errors which did not
appear two(?) days ago.

  error: variable-size type declared outside of any function
  error: variable-size type declared outside of any function

I assume the diagnosis as such is correct, but the fact that it is issued
twice doesn't seem to be.

I believe this is a consequence of the following patch.

I am testing a patch that will change the diagnostics to

warning: variably modified 'b' at file scope

appearing exactly once (this is a pedwarn, so an error with -pedantic-errors).
