bug#6812: 24.0.50; Inadvertant name capture (more information)

Compiling from bzr repository
gcc -c  -Demacs -DHAVE_CONFIG_H  -I. -I/jpff/GNU_21/emacs/trunk/src

make: *** [src] Error 2

Looking at /usr/include/gpm.h it says about line 120

typedef struct Gpm_Event {
  unsigned char buttons, modifiers;  /* try to be a multiple of 4 */
  unsigned short vc;
  short dx, dy, x, y;
  enum Gpm_Etype type;
  int clicks;
  enum Gpm_Margin margin;
  short wdx, wdy;
}              Gpm_Event;

Running -E on the compilation this becomes

typedef struct Gpm_Event {
  unsigned char cur_term->type. Numbers[30], modifiers;
  unsigned short vc;
  short dx, dy, x, y;
  enum Gpm_Etype type;
  int clicks;
  enum Gpm_Margin margin;
  short wdx, wdy;
} Gpm_Event;

and the buttons field has change to something unsyntactic.  Initial
searching has not found where this comes from, but somehow "buttons"
has become "cur_term->type. Numbers[30]".  It was OK yesterday

Extra information...

Just thought to look in /usr/include
/usr/include/term.h:#define buttons                        CUR Numbers[30]

That means the interaction is between <term.h> and <gpm.h>
This is not the area I understand
