compile error wrt VERSION

At a 32 bit stable Gentoo Linux I do get (using make -j4):

gical-op -Wstrict-aliasing=3  -o devices.o -c devices.c
In file included from debug.c:13:0:
include/version.h:3:9: error: macro names must be identifiers
debug.c: In function ‘__BUG’:
debug.c:44:23: error: ‘VERSION’ undeclared (first use in this function)
debug.c:44:23: note: each undeclared identifier is reported only once for each function it appears in
make: *** [debug.o] Error 1
make: *** Waiting for unfinished jobs....
