>How-To-Repeat:

$ cat a.c
#ifdef BLAH
#elif
#endif

$ cc -E -DBLAH a.c
# 1 "a.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "a.c"

$ gcc44 -E -DBLAH a.c
# 1 "a.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "a.c"
a.c:2:6: error: #elif with no expression

However, if you don't define BLAH then cc from base complains, too.
