In expread.y parse_number, there is existing code that should accept
'L','l','u', or 'U' at the end of a number; however, the current
yylex does not let these through, so the code is seemingly useless.
The following lines of code can be added in yylex immediately following
the comment:
  /* This is the sign of the exponent, not the end of the
      number.  */
and will allow 'l' or 'L' at the end of integer or hex constants, and will
allow 'u' or 'U' at the end of integer constants. Jay Norwood

   ++p; break;
