With gcc 3.3.3 (from NetBSD 3) I get this

  cc -std=gnu99 -pthread -Wall -Wformat=2 -Wstrict-aliasing -Wfloat-equal

  : undefined reference to `LZMA_CRC32_TABLE'
  In function `lzma_crc64':
  : undefined reference to `LZMA_CRC64_TABLE'
  *** Error code 1

Using 'gcc -E' shows that the preprocessor does not replace LZMA_CRC32_TABLE
in crc32.S (and LZMA_CRC64_TABLE in crc64_x86.S) in this context (the
non-PIC case):

   movl    $LZMA_CRC32_TABLE, %ebx

   # 121 "check/crc32_x86.S"
        movl $LZMA_CRC32_TABLE, %ebx

  $ nm work.i386/xz-4.999.9beta/src/liblzma/liblzma_la-crc32_x86.o
           U LZMA_CRC32_TABLE
  00000000 T lzma_crc32

The file that libtool/gcc creates  for the shared library with "-fPIC -DPIC"
looks correct and has no problem linking successfully

  $ nm work.i386/xz-4.999.9beta/src/liblzma/.libs/liblzma_la-crc32_x86.o
  00000000 T lzma_crc32
           U lzma_crc32_table

Relaxing the requirement from gcc 3.4 to gcc 3.3.6 (Tobias Nygren does
not see the problem with 3.3.6 on x86_64) does not work for me, I get
the same error.
