Here's how Lattice 5.02 handles it:

_main 0000-00

SECTION 00 "test.c" 00000020 BYTES
;   1: void
;   2: main()
;   3: {
       | 0000  4E 55 FF FA                    LINK      A5,#FFFA
;   4:   char *list;
;   5:   char c;
;   6:   c = '8';
       | 0004  1B 7C 00 38 FF FB              MOVE.B    #38,FFFB(A5)
;   7:   list = &c;
       | 000A  41 ED FF FB                    LEA       FFFB(A5),A0
       | 000E  2B 48 FF FC                    MOVE.L    A0,FFFC(A5)
;   8:   c = (list,*list);
       | 0012  20 6D FF FC                    MOVEA.L   FFFC(A5),A0
       | 0016  1B 50 FF FB                    MOVE.B    (A0),FFFB(A5)
;   9: }
       | 001A  4E 5D                          UNLK      A5
       | 001C  4E 75                          RTS

Seems much more straight forward.
