File: [cvsweb.bsd.lv] / mandoc / roff_html.c (download)

Revision 1.21, Mon Jun 22 19:20:40 2020 UTC (6 months, 3 weeks ago) by schwarze
Branch: MAIN
CVS Tags: HEAD
Changes since 1.20: +3 -1 lines

Because mandoc_aux.h and mandoc.h use __attribute__, all files that
include mandoc_aux.h or mandoc.h need to include config.h, too.
It is suspected that for example IRIX needs this, or it is likely
to throw errors in these files because the system compiler doesn't
understand __attribute__.
