Bug Report for GCC:
-------------------
Problem :  gcc 1.28 -O produces assembly code on the sparc that is disagreeable
	        to the assembler.  I wish I could be more specific as to the
           line of source code responsible for this, but I don't read
           sparc asm (yet).  The assembly code, annotated at the site
           of the complaint, is enclosed below.

1.) Version : gcc 1.28
-----------

2.) Input Program :
-----------------
s22(pd0)                 /* 2.2 Identifiers (Names)      */
   struct defs {
     int cbits;          /* No. of bits per char           */
     int ibits;          /*                 int            */
     int sbits;          /*                 short          */
     int lbits;          /*                 long           */
     int ubits;          /*                 unsigned       */
     int fbits;          /*                 float          */
     int dbits;          /*                 double         */
     float fprec;        /* Smallest number that can be    */
     float dprec;        /* significantly added to 1.      */
     int flgs;           /* Print return codes, by section */
     int flgm;           /* Announce machine dependencies  */
     int flgd;           /* give explicit diagnostics      */

     int crc;            /* Cumulative return code         */
     char rfs[8];        /* Return from section            */
   };

   char *ps, *pt;
                         /* Initialize                      */

   rc = 0;
   ps = qs22;
   pt = pd0 -> rfs;
   while (*pt++ = *ps++);

     /* An identifier is a sequence of letters and digits;
        the first character must be a letter. The under-
        score _ counts as a letter.                        */

   a=1;
   _=2;
   _234=3;
   a234=4;
   if(a+_+_234+a234 != 10) {
     rc = rc+1;
     if(pd0->flgd != 0) printf(s22er,1);
   }

   /* Upper and lower case letters are different.     */

   A = 2;
   if (A == a) {
     rc = rc+4;
     if (pd0->flgd != 0) printf(s22er,4);
   }

   return(rc);
}
