c/4890: inconsistent int-to-pointer warning

Hi,

I can confirm that this is still present in gcc-3.2. I can't reproduce
with recent 3.3, don't know about 3.2.1 yet. The problem is not arch
specific.

Here are instructions on how to reproduce this with a much smaller
testcase:

touch /usr/include/empty.h
echo '#include <empty.h>' >t.c
gcc -traditional -E t.c
# 1 "p.c"
# 1 "/usr/include/empty.h" 1 3
# 2 "p.c" 2 3

The last line is the problem: ``# 2 "p.c 2 3'' means:
                                  ^  ^   ^ ^
                                  |  |   | |
New line number is 2 -------------+  |   | |
New file name is p.c ----------------+   | |
Event was LC_LEAVE   --------------------+ |
We are returning to SYSTEM header ---------+

The last part is clearly wrong. Also this is a regression from 2.95.3
