Here's an annoying cpp bug that seems to have been around for
a while. I'm on a 3B2 running Vr3:
$ what /lib/cpp
/lib/cpp:
/lib/cpp.sl 1.13 4.2 05/14/87 11610 AT&T-SF
$ cat tst.c
#define SQUARE(x) ((x) * (x))
#define CUBE(x) ((x) * (x) * (x))
void exit();
main()
{
int a, b;
a = 3;
b = SQUARE(
a) + CUBE(
a);
printf("%d\n", b);
exit(0);
}
$ /lib/cpp tst.c
# 1 "tst.c"
void exit();
main()
{
int a, b;
a = 3;
b = (( a) * ( a)) + # 13 "tst.c"
(( a) * ( a) * ( a));
# 14 "tst.c"
printf("%d\n", b);
exit(0);
}
$
Naturally the output won't compile with "# 13" in the middle of
a line. Does anybody have a fix for this?
