For the files: The assembler fails because of:

#  if defined(sun) || defined(mc68k)
#    define imm(data)   #data
#  else
#    define imm(data)   \#data
#  endif

in lib/match.c. The preprocessor (gcc 4.7) makes "data" or \"data" from  
that, when it should be #data.

By setting

ASCPPFLAGS='-traditional-cpp -Dmc68k'

in configure ("# Try to assemble match.S.") and lib/Makefile the assembler  
succeeds. All 68k-based targets should be affected by this. But I did not  
notice any significant compression-speed-improvement in the  
assembler-version of gzip, so I'm not sure if it's worth the effort.
