Can anyone help me figure out this error?

C:\djgpp\ALLEGRO\EXAMPLES>gpp ex22.c
ex22.c: In function `int main()':
ex22.c:454: no match for `++{anonymous enum} &'

this is from the ex22.c example in the allegro\examples folder.


Line 454 says :

450      if (keypressed()) {
451  if ((readkey() & 0xFF) == 27)
452     break;
453  else {
454     ++render_mode;
455     if (render_mode >= last_mode)
456        render_mode = wireframe;
457   }
458     }
459   }


I am assuming it has something to do with enumeration but I haven't been
able to put my finger on the problem.

I have tried compiling it with gcc, and also by including the -lalleg option
for both gcc and gpp, still I am
unable to figure this out.


This is the part about enumeration if this helps any

79 enum

80   wireframe,
81   flat,
82   gcol,
83   grgb,
84   atex,
85   ptex,
86   atex_mask,
87   ptex_mask,
88   atex_lit,
89   ptex_lit,
90   atex_mask_lit,
91   ptex_mask_lit,
92   last_mode
93 } render_mode = wireframe;

Thanks,

fox
