You can simply use $(gl_LIBOBJS) instead of @address@hidden  Problem
solved: backslash-newline outside of a rule command line is replaced
with a single space by 'make'.  In the long run you are IMVHO hindering
maintainability by allowing such usages now, instead of having them
found early and eliminated.

But I'll stop insisting now, do as you please.  ;-)
