Add #include of sys/types.h for .c files that include missing.h to be sure that size_t and ssize_t are defined. 2010-08-30 09:14:41 -04:00			`#include <config.h>`

Add guards in compat source files. Not really needed since we only include them in the Makefile if they are needed but should not hurt either. 2013-04-01 10:19:26 -04:00			`#ifndef HAVE_STRSIGNAL`

Make local includes consistent; use double quotes for local includes except for generated ones where we use angle brackets. Also g/c unused compat.h. 2010-09-07 16:45:19 -04:00			`#include "missing.h"`

Add gettext.h convenience header. This is similar to but distinct from the one included with the gettext package. 2011-05-20 11:48:17 -04:00			`#define DEFAULT_TEXT_DOMAIN "sudo"`
