New comment by 4ricci on void-packages repository https://github.com/void-linux/void-packages/pull/31350#issuecomment-856675205 Comment: The compilation error is caused by a missing space [here](http://mpg123.org/cgi-bin/scm/mpg123/trunk/configure.ac?r1=4894&r2=4900#l1442), which was fixed in a [later commit](http://mpg123.org/cgi-bin/scm/mpg123/trunk/configure.ac?r1=4940&r2=4945&diff_format=u), not yet part of a release.
