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"
__db_version
# 2 "test.c" 3 4
4
# 2 "test.c"
+0000;
