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:
