Debian Compile still bombs on gw__scm_extras

[Andrew Sackville-West]

gw-engine.c: In function 'gw__tmp426_xaccQueryAddDateMatch_wrapper':
 > gw-engine.c:16686: warning: 'gw__scm_extras[0]' is used uninitialized in
 > this function

how hard is it to fix this thing?

I know the workaround CFLAGS="-Wno-unitialized", but always forget the 
sucker. is it as simple as
define gw__scm_extras
somehwere?
