I use the GCC pre-processor to abstract away from the details of a language
implementation.  In it, I need to reference a symbol with an array-like
syntax, such as V2[2], which I abstract away from using a macro: dreg_x(V2,
2).  This macro is defined as:

  #define dreg_x(dreg, index) dreg[index]

When simply used, this generates what I want:

	dreg_x(V2, 2) == V2[2]

but when used with a space after the first argument, it adds a space in
the expansion:

	dreg_x(V2 , 2) == V2 [2]

Is this OK for ANSI C or is it a bug?

P.S.  I have a workaround to this case. so you don't need to send me one.
