Not a gcc bug, the ITS report proved incomplete. gcc-5 inserts
"# <file information>" lines (indicating where the macro
expansion comes from, I think), so it needs the line breaks.

This slightly different test program:

#include <db.h>
__db_version DB_VERSION_MAJOR+0000;

...produces this:

# 2 "test.c"
# 2 "test.c" 3 4
# 2 "test.c"
