Subject: liblzma: Fix compilation of fastpos_tablegen.c.
X-Git-Tag: v5.5.1alpha~85
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=46007049cd42e606543dbe650feb17bdf4469c29;p=thirdparty%2Fxz.git

liblzma: Fix compilation of fastpos_tablegen.c.

The macro lzma_attr_visibility_hidden has to be defined to make
fastpos.h usable. The visibility attribute is irrelevant to
fastpos_tablegen.c so simply #define the macro to an empty value.

fastpos_tablegen.c is never built by the included build systems
and so the problem wasn't noticed earlier. It's just a standalone
program for generating fastpos_table.c.

Fixes: https://github.com/tukaani-project/xz/pull/69
Thanks to GitHub user Jamaika1.
