touble building liferea-1.0.12

[Keith Beattie]

When building port liferea-1.0.12, I get:

zlib_interface.c: In function `jg_gzip_uncompress':
zlib_interface.c:180: error: syntax error before "xlen"

line 180 is:
  ssize_t xlen = (data_start[1] << 8) | data_start[0];

if I change it to size_t, it builds but I'm hesitent to install it
that way as on other machines the port builds and installs properly.

Any thoughts on what might be wrong on this one machine?

Thanks,
