Compiling from bzr repository
gcc -c  -Demacs -DHAVE_CONFIG_H  -I. -I/jpff/GNU_21/emacs/trunk/src     -I/usr/include/alsa          -MMD -MF deps/sysdep.d  -Wimplicit-function-declaration -Wold-style-definition -Wdeclaration-after-statement -Wno-pointer-sign  -g -O2 -fno-optimize-sibling-calls sysdep.c
In file included from termhooks.h:310:0,
                 from sysdep.c:107:
/usr/include/gpm.h:120:17: error: expected ?:?, ?,?, ?;?, ?}? or ?__attribute__? before ?->? token
make[1]: *** [sysdep.o] Error 1
make[1]: Leaving directory `/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

It is a monumental stupidity in the ncurses header file, almost criminal.
On Mandriva there is an #ifdef __INTERNAL_CAPS_VISIBLE around
these #defines, but I see not all distributions have them (Suse and Fedora
does not for example).

I checked in a fix.

Thanks for investigating this.
