 I'm not sure your mechanism is lynx-friendly, so I'll include them
 here as plain text.  Sorry for the inconvenience.
 
 I get an internal compilation error when using
 gcc version 2.95.3 20010315 (release)
 to compile this code, whether or not I use -Wall or -save-temps.  I use no
 other switches, no includes, just a straight compile.
 
 === code begins immediately after this line
 #define X(a) if(a);
 
 int main(void) { long long little_doggie;
 
 /*
  * It makes no difference whether the offending expressions are surrounded by
  * () or (()).  I used (()) because of your suggestion to check the
  * compilation against -Wall.
  */
 
    X((little_doggie=0x01030507090B0D0FLL)) /* internal error */
 /* X((little_doggie=0x01030507090B0D0FL))     internal error */
 /* X((little_doggie=0x01030507090B0D0F))      internal error */
 /* X((little_doggie=0x0103050709))            internal error */
 /* X((little_doggie=0x01030507))              compiles ok    */
 
 return 0; }
 
 === code ends immediately before this line
 
 The output I get is this:
 
 /tmp/e1.cxx: In function `int main()':
 /tmp/e1.cxx:11: Internal compiler error in `do_jump', at expr.c:10976
 Please submit a full bug report.
 See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
 
 The output from the -v switch is this:
