Actually, it is, namely in src/lzw/ftlzw.c.

If FT_CONFIG_OPTION_USE_LZW isn't set, the function FT_Stream_OpenLZW
is replaced with a dummy which always returns
LZW_Err_Unimplemented_Feature.  Anyway, I've now patched ftlzw.c to
load zopen.h only if this macro is defined (zopen.c was already
handled this way).

Your patch is not necessary, I think.  Please try the CVS again.

It would be great if you can find time to do that.
