 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
 
     regards   Christian
