Subject: bug:

----------------------------------------------------------------------
#define hexCh(c (c >= 10 ? 'a' + c - 10 : '0' + c)
  hexCh(c);

out:
jiang@jiang:~/test$ ./tcc -E c4.c
# 1 "c4.c"

(c >= 10 ? 'a' + c - 10 : '0' + c);
---------------------------------------------------------------

#define hexCh(c/3) (c >= 10 ? 'a' + c - 10 : '0' + c)
hexCh(c);

out:
jiang@jiang:~/test$ ./tcc -E c4.c
# 1 "c4.c"

/3) (c >= 10 ? 'a' + c - 10 : '0' + c);
jiang@jiang:~/test$

after patch:

# 1 "c4.c"
c4.c:1: error: may not appear in macro parameter list: "("
jiang@jiang:~/test$

jiang@jiang:~/test$ ./tcc -E c4.c
# 1 "c4.c"
