bug#33856: PATCH: switch to non-recursive makefile

[Paul Eggert]

Thanks for starting on that. The bin_PROGRAMS thing is computed automatically in 
coreutils, but is overkill for gzip. You might try adding 'bin_PROGRAMS = gzip' 
to cfg.mk.

I ran into a different problem with that patch. When I configured with 
--enable-gcc-warnings, I got:

  CC       lib/malloca.o
lib/malloca.c:18:0: error: macro "_GL_USE_STDLIB_ALLOC" is not used 
[-Werror=unused-macros]
 #define _GL_USE_STDLIB_ALLOC 1

and this is most likely a shortcoming in Gnulib that would need to be fixed 
there.
