and had 'Segmentation Fault' in make check.

% ./configure CC=cc CFLAGS='-m64 -g'

Thanks for reporting that. This exposed some bugs in configure.ac and lib/match.c: the configuration procedure assumes that, since cc assembles x86 instructions successfully, the x86 code will actually work when called from x86-64 code. I fixed this by installing the attached patch.

Also, since -m64 affects the preprocessor output, you need to set CPPFLAGS and/or put the -m64 into CC instead. Something like the following should work with gzip 1.7:

./configure CC='cc -m64' CFLAGS='-g' DEFS='-D NO_ASM'

(A space is required between '-D' and 'NO_ASM'.) With the patch, plain './configure CC="cc -m64" CFLAGS=-g' should also work.
